The known registry setting in
LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Console\TrueTypeFont
Allows you to add font by having the Value Name to be a multiple of 0 and Value Data to be the font name. But this is not the case when East Asian language (e.g. Korean) is used for non-Unicode programs. I only have Raster Fonts and 굴림체 (Korean font) as my option. I have the following values in the registry:
0 Lucida Console 00 Consolas 932 *MS ゴシック 936 *新宋? 949 *굴림체 950 *細明體 So I have the fonts for, English, Japanese, Korean, and Chinese.
Under Command Prompt Properties. This is what I have:

Is it be possible to use other fonts like Consolas while still using Eastern Asian Language for non-Unicode programs?
