Hello Takamitsu,

You talk about “fonts” here. But don’t you perhaps mean “encodings”? After all if you want to change the font on some text, then you just change the font.

So I am assuming you are talking about legacy “fake-fonts”, i.e., fonts which display—usually the base-256 or “ASCII +”—characters with shapes inappropriate to their encoding value. If you want to change this kind of situation, you will need a table which maps the encoding values of the “fake font” to their proper encoding value in Unicode. Then you can store this table in a hash and use the macro command “.transliterateInRange” (there is also a newer “.transformInRangeWithICU” which may be useful for some cases, but probably not legacy fonts) to change any text in the relevant font. If this is the case you are looking for and you need help on how to do this, just let us know.

Cheers.
Philip
