IntlChar::charName — Retrieve the name of a Unicode character
Beschreibung
$codepoint, int $type = IntlChar::UNICODE_CHAR_NAME): ?stringRetrieves the name of a Unicode character.
Depending on type, the resulting character name is the "modern" name or the name that
was defined in Unicode version 1.0. The name contains only "invariant" characters like A-Z, 0-9, space, and '-'.
Unicode 1.0 names are only retrieved if they are different from the modern names and if ICU contains the data for them.
