The '''_MAPUNICODE''' function returns the [[Unicode]](UTF32) code point value of a mapped [[ASCII]] character code.
|
|
|
|
|
|
|
|
{{PageSyntax}}
|
|
:: UTFvalue& = _MAPUNICODE(Ascii_code%)
|
|
|
|
|
|
* The UTF32 values have 4 byte encoding so the return variable should be [[LONG]].
|
|
* The ''Ascii_code'' can be any [[INTEGER]] value from 0 to 255.
|
|
* Returns can be used to verify or catalog the present Unicode mapping.
|
|
* The function will return Unicode values for the control characters, CHR$(127) and extended characters '''without mapping''' them first.
|
|
|
|
|
|
''Example:'' Store function return values in an array for ASCII codes 0 to 255 to restore them later.
