{{DISPLAYTITLE:_MAPUNICODE (function)}}
|
|
The [[_MAPUNICODE]] function returns the [[Unicode]] (UTF-32) code point value of a mapped [[ASCII]] character code.
|
|
|
|
|
|
{{PageSyntax}}
|
|
: {{Parameter|utfValue&}} = [[_MAPUNICODE]]({{Parameter|asciiCode%}})
|
|
|
|
|
|
{{PageDescription}}
|
|
* UTF-32 values have 4-byte encoding so the return variable should be [[LONG]].
|
|
* The {{Parameter|asciiCode%}} can be any [[INTEGER]] value from 0 to 255.
|
|
* Returns can be used to verify or catalog the present Unicode mapping.
|
|
* The function returns Unicode values for the control characters, CHR$(127) and extended characters without mapping them first.
