was specifically developed to handle Vietnamese characters.

is a single-line description and usage guide for a SHX (AutoCAD shape/font) file that provides Vietnam-specific glyphs mapped to the VN-UNI encoding. The following content is ready to use in documentation, a font repository, or a download page.
