Windows-1258
From Free net encyclopedia
Windows-1258 is a codepage used in Microsoft Windows to represent Vietnamese texts. It makes use of combining diacritical marks. Windows-1258 is not compatible with VISCII. It is very similar to windows-1252 with the differences being that s-caron and z-caron (which were added to windows-1252 later) are missing, four of the letters with diacritics have been replaced by combining diacritics and a few other letter/diacritic combinations have been replaced.
Use of combining diacritics means that windows-1258 can cover the large number of letter/diacritic combinations in Vietnamese without compromising coverage of control codes or symbols.
Codepage layout
Only the upper half (128–255) of the table is shown, the lower half (0–127) being plain ASCII. Combining diacritical marks are shown applied to a plus sign e.g. +̀ and the cells they are in also have a pink background. Other differences from windows-1252 are indicated with a light blue background NBSP and SHY refer to the non-breaking space and soft hyphen respectively.
