Parameters
| ch | - | character |
| loc | - | locale |
Return value
Returns the lowercase form of ch if one is listed in the locale, otherwise return ch unchanged.
Notes
Only 1:1 character mapping can be performed by this function, e.g. the Greek uppercase letter 'Σ' has two lowercase forms, depending on the position in a word: 'σ' and 'ς'. A call to std::tolower cannot be used to obtain the correct lowercase form in this case.
