func Fold ¶
- Case folding is similar to lowercasing.
- The result may be a simple mapping, i.e., a single code point, or
- a full mapping, i.e., a string.
- If the case folding for a code point is the same as its simple (1:1) lowercase mapping,
- then only the lowercase mapping is stored. *
- Some special cases are hardcoded because their conditions cannot be
- parsed and processed from CaseFolding.txt. *
- Unicode 3.2 CaseFolding.txt specifies for its status field:
# C: common case folding, common mappings shared by both simple and full mappings. # F: full case folding, mappings that cause strings to grow in length. Multiple characters are separated by spaces. # S: simple case folding, mappings to single characters where different from F. # T: special case for uppercase I and dotted uppercase I # - For non-Turkic languages, this mapping is normally not used. # - For Turkic languages (tr, az), this mapping can be used instead of the normal mapping for these characters. # # Usage: # A. To do a simple case folding, use the mappings with status C + S. # B. To do a full case folding, use the mappings with status C + F. # # The mappings with status T can be used or omitted depending on the desired case-folding # behavior. (The default option is to exclude them.)
- Unicode 3.2 has 'T' mappings as follows:
0049; T; 0131; # LATIN CAPITAL LETTER I 0130; T; 0069; # LATIN CAPITAL LETTER I WITH DOT ABOVE
- while the default mappings for these code points are:
0049; C; 0069; # LATIN CAPITAL LETTER I 0130; F; 0069 0307; # LATIN CAPITAL LETTER I WITH DOT ABOVE
- U+0130 has no simple case folding (simple-case-folds to itself).
