Not all characters can be converted between Unicode and other non-Unicode code pages. Therefore, some characters are converted into error characters. For additional information on error characters, see Chapter 8 in International Character Set Support (B035-1125). In most cases, conversion errors result in the following Teradata Database errors:
  • 6706 – The string contains an untranslatable character
  • 6705 – An illegally formed character string was encountered during translation

In some cases, the “?” is used as the error character. In these cases, Teradata Database cannot detect conversion errors. Therefore, SQL-Text and character strings should match the session character set repertoire to avoid conversion errors.
