See my previous reply.

Err, that depends on what API layer you're working with. (For example:
svn_fs.h is perfectly happy with :,*,\n as part of the basename, but
libsvn_wc on windows, and the mergeinfo logic, aren't.)

And 'what to encode/decode' is a rather vague question. I'm not sure if
it means "Does `svn info uri:///foo bar` == `svn info uri:///foo%20bar`?"
or something else. Can you be more concrete?
