Bug #: 31191
           Summary: All 'Sona Hanabira ni Kuchizuke wo' games fail to
                    start because of wine buggy string compare
                    implementation.
           Product: Wine
           Version: 1.5.8
          Platform: x86
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: kernel32
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]
    Classification: Unclassified

The engine of Sona Hanabira (among other many games) does use indexed container
files for retrieving game resources.

Having a key of type string, it performs binary search within the index to find
the resource pointers.

But, because of buggy string compare APIs implementation in wine (mainly
StringCompare and StringCompareEx, which are called by lstrcmp and lstrcmpi),
comparison returns wrong values, and the seek fail.

At the moment, wine is just comparing DUCET values of each character (which is
wrong in very many cases), and ignoring several possibilities of StringCompare
API (like IGNORE_KANATYPE, i.e.). Some of them may apply to this bug, some may
not. Anyway, it is broken.

For Sona Hanabira games, a workaround is to use this patcher which reorder
index entries in the way Wine currently (wrongly) look for them:
http://vn.i-forge.net/tools/#sono+hanabira+ni+kuchizuke+wo%C2%B1+linux+wine+...

This bug report is to (hopefully) avoid the need of that patch in the future.

Does that app have a home page? 
Is there a downloadable app that suffers from this same hang/crash/abort?

It does have a home page, but it's quite broken right now. No downloadable
test, AFAIK.

On the other hand, reading the index entries, I have noticed that all of them
are plain ascii, with no more than [A-Za-z_.].

I wrote a little experiment (http://pastebin.com/DYkyPvAR) and run it both in
wine and windows. This is the result: http://mergely.com/eHJ1cHwW/

There can be noticed that order of '_' and '.' (characters which are used in
the index) are reversed in order, among others. That might be the cause of the
crash.
