For Vietnamese, Emacs uses special charsets internally.
They can be decoded from and encoded to VISCII, VSCII, TCVN-5712, and
VIQR. VSCII is deprecated in favour of TCVN-5712. Current setting
2003-02-11 17:06:46 +00:00
puts higher priority to the coding system VISCII than TCVN-5712. If
you prefer TCVN-5712, please do: (prefer-coding-system 'vietnamese-tcvn).
There are two Vietnamese input methods: VIQR and Telex, VIQR is the
default setting.")
