The _MAPUNICODE function returns the Unicode (UTF-32) code point value of a mapped ASCII character code.
Syntax
- utfValue& = _MAPUNICODE(asciiCode%)
Description
- UTF-32 values have 4-byte encoding so the return variable should be LONG.
- The 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.
Examples
Example: Store function return values in an array for ASCII codes 0 to 255 to restore them later.
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 |
