Isn't this the default encoding of a PostScript (text) file using standard encoded fonts?

The situation can be different once you re-encode the font, then the PS file's text encoding has to follow. If the font is re-encoded in ISO Latin-1 then the PS code has to use it too. Same for every other 8-bit font re-encoding (I have no idea how it works with CJK). The characters that are allowed to be used as PostScript code are taken from US-ASCII. So the code is independent from the text encoding. Care has to be taken when texts in an 8-bit encoding should be output, or printed, usually enclosed in parentheses. The text encoding has to match the font encoding, or the font encoding (of the user-defined font) has to be prepared for the text encoding to be used below.
