utf8.char

pattern

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

Declaration
export switch function 
      char overlong-handling value error-handling-type overlong-handling optional

    


Purpose

The function utf8.char matches UTF-8 encoded characters in its #current-input. By default, or if the overlong-handling variable is specified as not-allowed, it matches only the shortest possible encoding, and overlong values are not matched. If the argument is specified as not-allowed-with-throw, an overlong value will trigger a throw of the utf8.overlong-sequence exception.

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