F.10 Character Set Functions

XmuCopyISOLatin1Lowered copies a null-terminated string (including the null), changing all Latin-1 uppercase letters to lowercase. XmuCopyISOLatin1Uppered copies a null-terminated string (including the null), changing all Latin-1 lowercase letters to uppercase. XmuCompareISOLatin1 compares two null-terminated Latin-1 strings, ignoring case differences, and returns an integer greater than, equal to, or less than 0, according to whether first is lexicographically greater than, equal to, or less than second. In all three of these routines, the string is assumed to be encoded using ISO 8859-1.

The following functions have the same arguments and function as XLookupString(), except that they convert to keysyms in different sets.
