RE: iCalendar - "octets" question

Probably MAY, rather than SHOULD.

>Does this have any potential problems?

It shouldn't; folding and unfolding lines is defined to be irrelevant to 
the semantics of the lines, which means that the simplest way to do it is 
to do it below the level of the parser/lexer.  By the time the lines reach 
the parser, they've been unfolded.

One reason to make sure that splitting characters is explicitly permitted 
is that there are legitimate cases in which the code that folds the lines 
doesn't actually know it's using multibyte characters.  For example, the 
iCalendar implementation I did for eCal didn't contain any explicit 
character-set code; it was assumed that all the character sets we would 
support sending would be supersets of ASCII.  The code that did a MIME 
wrapper could tag the object as, say, UTF-8, but there was no need for the 
code that generated the lines to understand UTF-8; it just used whatever 
strings it was given.
