From: goetter@xxxxxxxxxxxxxxxx CHAR-{UP,DOWN}CASE can work correctly as-is in Unicode as long as the program is working with decomposed character input - the most common case. Heh? What about Latin-1's es-szet? Decomposing turns it into "ss" for sure? Or leaves it as es-szet? What is done with downcasing Unicode's position-sensitive Greek letters? I think the sleazes I specify for patching CHAR-{UP,DOWN}CASE are acceptable, but they are sleazes nontheless: - CHAR-UPCASE maps es-szet to es-szet. - Position-sensitive Greek letters get mapped to the general, non-final variant. (And since these two procs are *not* part of SRFI-13, it's a side issue, though one worth discussing.) -Olin
