iswfc() checks the uppercase character for a mapping to foldcase, returning the number of new wide character codepoints needed.

The usual iswupper(wc) case returns 1, and the special 104 full folding cases as specified in Unicode 10.0 CaseFolding.txt return either 2 or 3.

Parameters
[in]wcunicode character codepoint
Return values
0when there is no corresponding lowercase mapping.
1when there is a corresponding common or simple foldcase mapping.
2a full case-folding expands to 2 characters
3a full case-folding expands to 3 characters
