A collating symbol is a collating element enclosed within bracket-period (
"[." and ".]" ) delimiters. Collating elements are defined as described in
Collation Order . Conforming applications shall represent multi-character
collating elements as collating symbols when it is necessary to distinguish
them from a list of the individual characters that make up the
multi-character collating element. For example, if the string "ch" is a
collating element defined using the line:

collating-element <ch-digraph> from "<c><h>"

in the locale definition, the expression "[[.ch.]]" shall be treated as an RE
containing the collating symbol 'ch' , while "[ch]" shall be treated as an RE
matching 'c' or 'h' . Collating symbols are recognized only inside bracket
expressions. If the string is not a collating element in the current locale,
the expression is invalid.
