Internationalisation and terminology changes

Detail:
  When generating the encoding menu the terms "Default" and "UTF8" were looked up via the Messages file, however the selection logic and update of the display field used hardwired English. Now, the internal variables Alphabet$ and Encoding$ are English but when required for display are always looked up.
  Now that works, use the preferred term "UTF-8" per Unicode consortium and Style Guide page 133.
Admin:
  From review of User Guide chapter.
