Public predicates

case_conversion/3

Converts a list of Unicode code points for a profile-specific case operation. Valid operations are fold, lower, upper, and title. Fails to select the library default Unicode behavior.

Compilation flags:

static

Template:

case_conversion(Operation,Codes,Converted)

Mode and number of proofs:

case_conversion(+atom,+codes,-codes) - zero_or_one

---

diacritic_fold/2

Maps a Unicode code point without a canonical base decomposition to a profile-specific replacement. Fails when no mapping is defined.

Compilation flags:

static

Template:

diacritic_fold(Code,Replacement)

Mode and number of proofs:

diacritic_fold(+code,-codes) - zero_or_one

---

named_entity/2

Maps a case-sensitive named character reference, without the leading ampersand or trailing semicolon, to Unicode code points. Fails for an unknown name.

Compilation flags:

static

Template:

named_entity(Name,Codes)

Mode and number of proofs:

named_entity(+atom,-codes) - zero_or_one
