      Charset

      Following is said about character sets:

      ACH file formats use the ASCII Character set. In XML messages, the UNICODE character set, encoded in UTF-8 (8-bit Unicode Transformation Format), is the official ISO 20022 character set that must be used. However, SWIFT added a rule to restrict the set of allowed characters to Basic Latin.
