* Additional criteria for Asian installations:
|
|
* - If it is not a TrueType font, the face name must be "Terminal".
|
|
* - If it is an Asian TrueType font, it must also be an Asian character set.
|
|
*
|
|
* To install additional TrueType fonts to be available for the console,
|
|
* add entries of type REG_SZ named "0", "00" etc... in:
