CorrectFarEastFont.cpp
|

|
|
Abstract:
|
||
|
|
|
||
|
|
Some localized Far East applications create font to display localized-
|
||
|
|
characters by supplying only font face name, and let the system pick up
|
||
|
|
the correct charset. This works fine on Win9x platforms. But on Whistler,
|
||
|
|
we need to specify correct charset in order to display localized characters
|
||
|
|
correctly.
|
||
|
|
|
||
|
|
We fix this in CreateFontIndirectA by correcting the charset value based on
|
||
|
|
font face name.
|
||
|
|
- If font face name contains DBCS characters, use the charset based on
|
||
|
|
System Locale (DEFAULT_CHARSET)
|
||
|
|
- If font face name is English or no face name is supplied,
|
||
|
|
use ANSI_CHARSET
