Re: Text that's not in any languagea

It might be interesting to know that the ISO 639-2 tag set that
is now under consideration includes tags for "unknown" and "multiple"
languages, but also excludes computer languages.

It was clear to me at the time that it's useful to keep the
distinction between natural language and computer language;
any non-French person who has tried to debug C code written
in French will appreciate that you sometimes want to tag
C code with a natural language!
