Bug ID: 53739
           Summary: [font cannot show in QQ ]When using the font
                    replacement function in the registry, some fonts
                    cannot be displayed, which affects normal use, and
                    even makes the response speed of some functions of the
                    application slow.
           Product: Wine
           Version: 7.16
          Hardware: x86
                OS: other
            Status: UNCONFIRMED

replacement.reg -> the registry file I modified fontwrong.log -> log of errors
that occurred

My English is not good, so I hope to be forgiven if there are any poor
wordings.

First of all, I appreciate your help and I will describe my problem in three
aspects.

[ Background of the problem ]
By using wine,I know that most of the font problems can be solved by installing
“allfonts” ect through winetricks,but I noticed that most of the fonts are not
open source.
So I want to use all open source fonts to display text in wine by my own
effort, such as NotoSans.
My ability does not support me to modify the source code directly, so I mainly
used the “Fonts\Replacements” function in the registry provided by wine to do
the replacement of missing\not open source fonts.
Most of the fonts displayed well after I made the replacements, but some fonts
had rendering problems, and these problems even affected the use of the
application.
Through my own research I found that all the changes I made to the registry did
not cause problems in wine 7.12, but in wine 7.18 they did.
By dichotomy, I found that the cause of the problem is the modification of the
file "dwrite", but I don't know where the problem occurs, so I'm asking for
advice.

[My actions]
The changes I made to the registry are in the file "replacement.reg", which you
can import directly from "./wine regedit."
I also deleted the fonts in . /wine/fonts file, because I want to display all
text in open source fonts.
In addition to changing the Fonts\Replacements in the registry and .
/wine/fonts file, I did not do any other things.
And I found that in my above operation, QQ can display all the text normally in
7.12, but not in 7.18.
[File description]
replacement.reg -> the registry file I modified
fontwrong.log -> log of errors that occurred
My model: ThinkPad-X1-Debian-11.4.0-amd64-KDE

I sincerely hope to get a reply, if you don't have time, you can simply point
me in the right direction, I'm also working on it now, hopefully we can make
wine better together

Ideally, it will be great to see bisect result - specific commit that causes
problems for you. The process is described here
https://wiki.winehq.org/Regression_Testing.

One of the recent changes to dwrite was an addition of fallback font list. That
list does use various Noto Sans fonts.

Are you sure QQ is using dwrite in a first place? WINEDEBUG=+dwrite will show
it.

First of all, I am honored to receive your reply !!! This is really inspiring
to me.
At the same time,I apologize for not responding to your message in time.
Through regression testing I found that the problem was caused by this commit,

dwrite: Remove old system fallback logic.
ID: 26e717c5653d2c6fcb29846e7d22aa97e37048e1

This commit seems to 'Remove old system fallback logic' and I am now looking at
why this commit is causing the problem and trying to fix it by myself.

In the meantime,by using WINEDEBUG=-all,+dwrite, I'm sure QQ is using dwrite.

I look forward to hearing from you.

Dear Nikolay Sivov：
    Through my attempts I found that the cause of the problem may be the
following: (everything below is based on the commit
"26e717c5653d2c6fcb29846e7d22aa97e37048e1")

'''bash
    $ git reset 26e717c5653d2c6fcb29846e7d22aa97e37048e1
'''

In "dwrite/analyzer.c", there is a problem with the
"fallback_map_characters" function, where the problem occurs as follows：

'''C
    2246:  data = fallback->data.count == ~0u ? &system_fallback :
&fallback->data;
'''

When I force  "data = fallback->data;"  the problem is solved.

So I guess there might be a problem with the assignment of
"system_fallback" or with data.count, and I'm still looking into the cause of
the problem.

For now, it seems that the brute force solution is to force "data =
&fallback->data;", but a more elegant solution is yet to be thought of.

No, I don't think you should be making such code changes to fix this. What I
don't  understand is why values are dumped as hex() in your reg file. And what
does it have to do with Noto Sans fonts.

Removing fonts from wine/fonts is not really supported, so please don't do
that. DirectWrite will try to use Tahoma by default, if everything else failed,
so you'll need Tahoma from wine installation.

I think you're right, it's true that we shouldn't actually fix the problem
by modifying the code in this way.

Q1:  why values are dumped as hex() in your reg file

I don't know why the value was converted to hex(). I just used the "export
registry" function provided by regedit and my registry was automatically
converted to that.

Incidentally, I found that I can edit the registry contents in
"wine.inf.in", but what should I do when the key value is Chinese?

When I type Chinese directly in the "wine.inf.in" file according to the
rules, the corresponding key value in the registry generates garbled code.

Q2: what does it have to do with Noto Sans fonts.

Since the registry value was changed to hex(), I am using a screenshot to
show what my registry actually looks like for your convenience.
    Image URL: https://imgse.com/i/x1ZM8g
————————————
    By the way, I would like to ask if there is any information that can help
me understand the dwrite code better.

I look forward to hearing from you.

Ok, it's probably because it's MULTI_SZ, and not just SZ.

I don't know what could be a problem with this list. If you don't remove
anything from wine/fonts (and you shouldn't), Tahoma replacement won't take any
effect, at least in dwrite. Because replacements are used after collection is
built, and only if name wasn't already added.

I think you are right，MULTI_SZ and SZ will produce different results.

I did delete all the fonts in the "./wine/fonts" folder because I don't
want to use copyrighted fonts.

You said before " DirectWrite will try to use Tahoma by default, if
everything else failed", I would like to ask if you can tell me how this is
implemented, is it through the file "dlls/dwrite/layout.c" line 733 ?

I'm thinking if I can modify the default specified font to Noto Sans fonts.

But when I type Chinese directly in the "wine.inf.in" file according to the
rules, the corresponding key value in the registry generates garbled
code,instead of the corresponding Chinese.

I really appreciate your help and I wish I knew if there was a way to express

Those are free fonts, provided by Wine project.

In current tree it's a function called layout_run_get_last_resort_font().

You can set it up in any way you want, what I'm saying is that Tahoma is our
current default font for UI, and for dwrite layout as well, so it's better to
leave it be.

I have no experience with that, sorry.

Thank you very much for your reply, this news helps me a lot.I have a few
questions and look forward to receiving your helps.

Q1: You said this is a free font, so I would like to ask if these fonts are
commercially available.

Q2:  I would like to ask if all the fonts under the "./wine/fonts" file are
free fonts, and my judgment that the fonts are copyrighted is only because the
font's familyname seems to be Microsoft's copyrighted fonts.Like tahoma, I
found out by searching that this is a Microsoft non-commercial font.

In wine, is it only the family name of fonts is the same as the Microsoft
non-commercial font,in fact, the internal font is made by our own wine.

Q3：You said "provided by Wine project.", I would like to ask where can I see
how these fonts are provided by wine? I am interested in fonts and I would like
to know if I can have a chance to be involved in the production of wine fonts,
so I would like to know how these "provided by Wine project" fonts are made.You
don't need to tell me exactly how it is done, it would be too much work for
you.
Just tell me which part of the project I should look at.

I'm a beginner in using wine, so I hope you don't mind if my question is
stupid.

I look forward to hearing from you.

Dear Nikolay Sivov：

I followed your advice and didn't delete anything in ./wine/font, but the
problem doesn't seem to be fixed.

And I found that "Text does not show in QQ UI" doesn't seem to be caused by
my modification. I use wine7.18 (just git pull, config, and make) without any
modification, and the problem still exists.

I have no idea what's happening. If it doesn't work correctly with clean
unmodifed installation - use official wine packages for that, and a new
wineprefix - then we could treat this as a new bug. Any local modifications are
hard to verify.

Is there a direct download link to the application? Is missing text problem
reproducible without a QQ account?

The QR code hangs the program (I have encountered this and I am sure the hang
problem is caused by dwrite(because When I use my way to let text show in
QQ,the hang problem is disappear))，I think you just need to wait a while
because the font does not display properly and the program is hang(I don't know
why cause caton),so you just need click the QR code and wait for a while,QQ
will automatically load a QR code and there is no font display below the QR
code,where should have some text.

(use plus sign button to find this problem is the quickest way,it will not
cause app hangs)

It is precisely because the font does not appear that the program responds
slowly (hangs), so I came to ask for your help.

If you don't see the plus sign button, try moving your mouse over the circular
penguin icon, which might show the plus sign.

Or I think you can enter the account password at will, and click to log in
(note that this will also cause a long period of hangs), and then QQ will
prompt you that the account password is wrong, but the text in this prompt also
cannot be show in wine.

Like the rest of Wine, our fonts are provided under the terms of the GNU Lesser
General Public License version 2.1. That fact is actually provided in the font
source and binary file, but may be nontrivial to discover. The basic provision
of the license is that you can use, modify, and redistribute the fonts, as long
as you make those modifications public to anyone you redistribute the fonts to.
You can read the license in its entirety here:
https://source.winehq.org/git/wine.git/blob/HEAD:/COPYING.LIB

Our fonts have the same name as Microsoft fonts by necessity, because programs
expect to open the Microsoft font by name.
