@CHAR[n] : Returns the character corresponding to a Unicode numeric value. If the parameter is a set of numeric values, CHAR returns a string. For example %@CHAR[65] returns A; %@CHAR[65 66 67] returns ABC.
To display the non-ASCII Unicode characters (>= 128), you need to be using a Unicode font in Take Command and/or TCC.
Numeric input may be entered in either decimal format (a sequence of 0-9 digits) or in hexadecimal format ("0x" followed by a sequence of 0-F hex digits).
Note: Not all characters are printable. High ASCII characters (128-255) and Unicode characters may vary depending on the font used.
Examples:
echo %@char[65]
A
echo %@char[65 97 66 98 67 99]
