Re: problems with german umlauts

well it was an approximation (due to the previously mentionned lack of vocabulary)
ISO 2022 (as well as SHIFT-JIS and other japaneses encoding of the same type) use indeed "artificial" 8bit characters.
The 0-127 range is always almost compatible with ASCII and there is 2 escaping character which work like double quotes. Inside quotes, character are multibyte (indeed it's impossible to store so many kanjis into only 128 slots)

But this option raises more issues than it brings solutions... even if it is still widely used in japan (ISO 2022 is still their default encoding for e-mailings)

Actually, there are much more.  If I'm not mistaken, the ISO 2022
registry has designed IDs to over 100 different 8bit character sets!

This isn't true in general.  For handling those languages separately,
16bit character sets work just fine.  Emacs demonstrates that, within
the ISO 2022 framework, multilingual work can be done quite
efficiently.

BTW, the value `36000' is not correct: The CNS 11643 character set
defines around 55000 Chinese characters, and the defunct CCCII
character set covered around 70000 characters (I have the books at
home -- it's almost a half meter on my bookshelf).
