Markus Scherer scripsit:
Note that even for single-language text you may need multiple script identifiers. For example, for Japanese text you will need 3 identifiers for Han+Hiragana+Katakana. Obviously, if you have multilingual text, you will need more.
Politely, ISO 15924 supplies a special code for this case.
