The entire premise of "Tai Font Vn-uni.shx" is a workaround for a legacy problem. In 2025 and beyond, using SHX fonts for multilingual text is considered an architectural debt. Tai Font Vn-uni.shx
Tai Font Vn-uni.shx 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.
