I'm not clear here. Is your requirement that you have to parse
"<asian characters here>"
Where the only non-US-ASCII characters appear between quotes? And that
the only restriction between those quotes is that it is a sequence of
vaild Unicode characters? If so, this is easily doable in with Antlr
in C++, if you take the treat your input as UTF-8.
If you need to support identifiers composed of non-US-ASCII characters,
it is a bit more difficult, but still doable.
This is exactly what I'm doing: My language is defined over the full
Unicode character set, allows Unicode in string literals, comments,
identifier names, and in a few cases operators (such as the U+F7, the
division sign). I lex and parse the language with Antlr, generating a
C++ lexer that accepts a UTF-8 encoded Unicode stream of bytes.
I'd be happy to share my work on this.

I think the time frame is longer than that.
