3 Case Folding
Implementation of case-folding based on UCD properties.
3.1 Module codepoint/fold
| (require codepoint/fold) | package: codepoint |
procedure
(ucd-case-folding c) → (hash/c symbol? (listof codepoint?))
c : codepoint?
Return the dictionary of case foldings for the source codepoint. The key to this
hash is one of the symbols from *case-folding-status*, and the value is
a list of new codepoints.
procedure
(case-fold-common c) → (listof codepoint?)
c : codepoint?
Applies the folding associated with the status 'common.
procedure
(case-fold-simple c) → (listof codepoint?)
c : codepoint?
Applies the folding associated with the status 'common, followed by the
folding associated with the status 'simple.
procedure
(case-fold-full c) → (listof codepoint?)
c : codepoint?
Applies the folding associated with the status 'common, followed by the
folding associated with the status 'full.
