VIQR

VIetnamese Quoted-Readable, usually abbreviated VIQR and also known as Vietnet, is a convention for writing Vietnamese using ASCII characters. Because the Vietnamese alphabet contains a complex system of diacritical marks, VIQR requires the user to type in a base letter, followed by one or two characters that represent the diacritical marks: Usage VIQR uses the following convention: VIQR uses DD for the Vietnamese letter Đ, and dd for the Vietnamese letter đ. To type certain punctuation marks (namely, the period, question mark, apostrophe, forward slash, opening parenthesis, or tilde) directly after most Vietnamese words, a backslash (\) must be typed directly before the punctuation mark, so that it will not be interpreted as a diacritical mark.
