C:\emacs-23.3\src>grep -E -o -h "\<\w+[a-z0-9]+W\>" w32font.c w32uniscribe.c | s
ort | uniq
DrawTextW
ExtTextOutW
GetGlyphOutlineW
GetOutlineTextMetricsW
GetTextExtentPoint32W
GetTextMetricsW
And in a wider search:
C:\emacs-23.3\src>grep -E -o -h "\<\w+[a-z0-9]+W\>" *.c | grep -v
"Elf\|MingW" | sort | uniq
AppendMenuW
DrawTextW
ExtTextOutW
GetFileSecurityW
GetGlyphOutlineW
GetOutlineTextMetricsW
GetTextExtentPoint32W
GetTextMetricsW
ImmGetCompositionStringW
LookupAccountSidW
lstrlenW
Note: The words that begin with Elf are macros, not functions.
I was going to report that the rest of these functions are already
implemented in core system libraries:
==================================================

==================================================
But I have stumbled across this comment:
w32menu.c:1505
/* On W9x/ME, unicode menus are not supported, though AppendMenuW
apparently does exist at least in some cases and appears to be
stubbed out to do nothing.[...] */
And then I have checked that both GetTextMetricsW and
GetOutlineTextMetricsW, which caused the system error #120 ("This
function is not supported on this system."), are actually
"implemented" in a core system library along with other of the
previous functions:
==================================================
Function Name : GetOutlineTextMetricsW
Address : 0xbff2795b
Relative Address : 0x0000795b
Ordinal : 286 (0x11e)
Filename : GDI32.DLL
Full Path : C:\WINDOWS\SYSTEM\GDI32.DLL
Type : Exported Function
==================================================
==================================================
Function Name : GetTextMetricsW
Address : 0xbff27952
Relative Address : 0x00007952
Ordinal : 315 (0x13b)
Filename : GDI32.DLL
Full Path : C:\WINDOWS\SYSTEM\GDI32.DLL
Type : Exported Function
==================================================
So, your idea of trying the unicode functions which have been
reimplemented in unicows.dll and seeing if they make a difference
looks very promising.
