Chữ Quốc Ngữ 用文字コード

[3] Chữ Quốc Ngữ (越南語ラテン文字表記) 用の文字コードは数多あります。

[27] 西暦1990年代まで各種符号が乱立していました。

[28] Web では VN3, VISCII, VNI, VPS が混在していました。 文字コードに近い翻字として VIQR もよく使われました。 ダイアクリティカルマークのない基本ラテン文字の代用表記もありました。

[29] 21世紀に入ってすぐに急速に UTF-8 への移行が進み、 西暦2004年2004頃にもなると主要サイトはあらかた Unicode 化されていた模様です。

[31] Web 以外ではその後も従来文字コードが残存していることがあるようです。

Convert VIQR query into VISCII, VPS, VNI and doing the same search

VIQR, VISCII query search (VPS, VNI may work but we have never tested)

VIS can "understand" Vietnamese in VIQR query. When it accepts a VIQR query, it will translate into VISCII, VPS, VNI and so on to find similar documents.

Send your article in VIQR, VISCII or VNLabs format if you're writing in Vietnamese; for English, plain ASCII would be much preferred.
