Reason (CharacterTranslationException property)

Enumerated cause of the exception (CharacterTranslationException class)

Syntax

%translationExceptionReason = characterTranslationException:Reason

Syntax terms

%reason	This TranslationExceptionReason enumeration value describes the reason for the translation failure.
%chTransEx	A reference to an instance of a CharacterTranslationException object.

Usage notes

• A TranslationExceptionReason enumeration may have one of the following values:

  InvalidEncoding

  An example of invalid encoding is UTF-16 string input to Utf16ToUnicode that contains bytes whose hexadecimal value is D800 (which is in the surrogates range).

  InvalidCharacterReference

  An XML-style hexadecimal character reference (for example, ™ for the trademark character) may validly represent a Unicode character to be translated. Any other string that begins with by an ampersand (&) — except the string & — might cause an exception explained by an InvalidCharacterReference enumeration. For example, such an exception occurs if EbcdicToUnicode is called, the method argument is CharacterDecode=True, and the method input contains an ampersand followed by a space.

  UntranslatableCharacter

  The following are examples of untranslatable characters (with the translation tables as delivered by Sirius):

  • The EBCDIC input to the EbcdicToUnicode method contains a byte whose hexadecimal value is X'FF.
  • The Unicode input to UnicodeToEbcdic contains one of the many Unicode characters that is not translated to an EBCDIC character (for example, U+20AC, the Euro currency symbol).

• As with all enumerations, you use the ToString method to convert an enumeration value to a character string whose value is the name of the enumeration value.
