The [_MAPUNICODE](_MAPUNICODE) function returns the [Unicode](Unicode) (UTF-32) code point value of a mapped [ASCII](ASCII) character code.
|
|
|
|
## Syntax
|
|
|
|
> utfValue& = [_MAPUNICODE](_MAPUNICODE)(asciiCode%)
|
|
|
|
## Description
|
|
|
|
* UTF-32 values have 4-byte encoding so the return variable should be [LONG](LONG).
|
|
* The asciiCode% can be any [INTEGER](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.
|
|
|
|
## Example(s)
|
|
|
|
Store function return values in an array for ASCII codes 0 to 255 to restore them later.
|
|
|
|
```vb
|
|
|
|
DIM Unicode&(255)
|
|
SCREEN 0
|
|
_FONT _LOADFONT("C:\Windows\Fonts\Cour.ttf", 20, "MONOSPACE") 'select monospace font
|
|
|
|
FOR ascii = 0 TO 255
|
|
Unicode&(ascii) = _MAPUNICODE(ascii) 'read Unicode values
|
|
PRINT Unicode&(ascii); 'display values in demo
|
|
NEXT
|
|
'rest of program
|
|
END
|
|
|
|
```
