pub fn is_word_character(c: char) -> boolExpand description
Returns true if and only if the given character is a Unicode word character.
A Unicode word character is defined by
UTS#18 Annex C.
In particular, a character
is considered a word character if it is in either of the Alphabetic or
Join_Control properties, or is in one of the Decimal_Number, Mark
or Connector_Punctuation general categories.
ยงPanics
If the unicode-perl feature is not enabled, then this function
panics. For this reason, it is recommended that callers use
try_is_word_character instead.
