The Vietnamese Quoted-Readable ( VIQR ) is a convention which makes it possible to write the Vietnamese on Internet by using only characters ASCII, for example when the Unicode is not available -   VIQR was created before unicode. Indeed, the writing Vietnamese (the Quôc ngu ) uses letter Romans with many Diacritique S (accents) who do not form part of the ASCII standard. The diacritic ones are represented by characters placed after the letters:

For the letter Đ , one uses DD or Dd, and for đ , one uses dd.

The characters indicating the diacritic ones being characters of Ponctuation, when one wants to put a punctuation mark after a letter, they should be separated by a bar from reversed fraction \ so that she is not interpreted like diacritic.

Example

• Sa ('c → Sắc
• Huye^ `n → Huyền
• Ho? i → Hỏi
• Nga~ → Ngã
• Na (.ng → Nặng
