Library: Character encodings, UTF-8 (OMUTF8 ) Import: omutf8.xmd

Return type: Integer Returns:  Integer value corresponding to the specified UTF-8 character.

Declaration

  define integer function utf8.code-point
    of  value stream utf8-string

You can use utf8.code-point to convert a string containing a single UTF-8 character to the character number it encodes.

If the string does not consist of a single UTF-8 encoded character, the character number of the Unicode Replacement Character (U-FFFD) is returned instead.

The following program converts a UTF-8 encoded file to a long character encoding (2 bytes for every character):

  import "omutf8.xmd" prefixed by utf8.

  process
      submit file #main-input

  find utf8.char => char
      output "2f0b" % utf8.code-point of char
