  86 For Vietnamese, Emacs uses special charsets internally.
  87 They can be decoded from and encoded to VISCII, VSCII, TCVN-5712, VIQR
  88 and windows-1258.  VSCII is deprecated in favour of TCVN-5712.  The
  89 Current setting gives higher priority to the coding system VISCII than
  90 TCVN-5712.  If you prefer TCVN-5712, please do: (prefer-coding-system
