According to my understanding, the 40-character limit is for charset
names used with RFC 1759 Printer MIBs and does not apply in general.
Seems wider: "These are the official names for character sets that may
be used in the Internet and may be referred to in Internet
documentation." And a few lines down: "The character set names may be
up to 40 characters taken from the printable characters of US-ASCII.
However, no distinction is made between use of upper and lower case
letters."
RFC 2978 doesn't specify a limit for mime-charset, but obviously
anything longer than 68 chars won't be useful for a 2047 encoded-word.
There are a couple of registered charsets with names a bit longer than
40 chars; the longest is 45 chars.
I suppose I'd avoid those, personally speaking. Inconsistencies are a PITA.
None of the registered names has *any* single quotes or percent signs.
And do _you_ think that will change? Does anyone here?
