Bug ID: 39298
           Summary: kernel32 does not support custom nls installation.
           Product: Wine
           Version: 1.7.51
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: kernel32
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

This is a somewhat related bug to 39297 - wine seems to use built-in code page
tables ( wine/libs/wine/c_*.c ) . On newer windows, code page 708 is shipped
with the OS; FontVal also bundle

CPinstall
CPinstall/i386
CPinstall/i386/c_852.nls
CPinstall/i386/c_1361.nls
CPinstall/i386/c_708.nls
CPinstall/i386/c_862.nls
CPinstall/i386/c_775.nls
CPinstall/i386/c_857.nls
CPinstall/i386/c_737.nls
CPinstall/i386/c_864.nls
CPinstall/i386/c_869.nls
CPinstall/CPinstall.inf
CPinstall.dll

for older windows which does not have them. However, I tried installing them
(via setupdll), it seems to popular the registry, and copy the nls files, but
does not seem to have any effect on wine's behavior at all.

FWIW, there seems to be only one nls file shipped with wine, l_intl.nls, that
if I remember correctly is required by dotnet; I don't seem to be able to find
any code which read nls files in wine at all.

Microsoft's FontValidator
(https://www.microsoft.com/typography/FontValidator.mspx)
when processing certain fonts, try to access code page 708,
which is not available under wine.

FYI, mono has support for code page 708 - c.f. mcs/class/I18N/Rare/CP708.cs .
