Module:Unicode convert/doc

Usage
Converts Unicode character codes, always given in hexadecimal, to their UTF-8 or UTF-16 representation in upper-case hex or decimal. Can also reverse this for UTF-8. The UTF-16 form will accept and pass through unpaired surrogates e.g.  →. The reverse function  accepts multiple characters, and can have both input and output set to decimal.

When using from another module, you may call these functions as e.g., without a proper   object.

To find the character code of a given symbol (in decimal), use e.g. →.
