in the command line and ensure your Text Style is explicitly set to use Vn-uni.shx Pro Tip for Portability
You might ask: Why not just use standard Windows Vietnamese TrueType fonts (like .ttf)?
In AutoCAD, fonts are divided into two main categories: TrueType Fonts ( .ttf ), which are standard Windows system fonts, and Shape Fonts ( .shx ), which are specialized vector fonts developed by Autodesk.
Vn-uni.shx is built for specific input methods. If the original text was typed using an incompatible software encoder (like Unikey with the wrong charset selected), the characters break. Tai Font Vn-uni.shx
In engineering and architectural projects within Vietnam, older drawings often use legacy font encodings like TCVN3 (ABC) or VNI. bridges the gap by allowing users to type and display Vietnamese characters using modern Unicode standards within the AutoCAD environment.
The use of represents a specialized chapter in the evolution of Computer-Aided Design (CAD) within Vietnam, bridging the gap between legacy text encoding and modern drafting requirements. Technical Foundation
The name of the font is a direct indicator of its purpose and capabilities. Let's break it down piece by piece: in the command line and ensure your Text
is a compiled SHX font file, a format developed by Autodesk. Unlike TrueType fonts (.ttf) which are managed by Windows, SHX fonts are managed directly by AutoCAD, making them highly efficient for displaying text in drawings.
Avoid mixing multiple Vietnamese encoding standards (such as VNI, TCVN3, and Unicode) within a single project layout. Stick strictly to Unicode-compliant styles for modern cross-platform data exchanges.
: Drag and drop your Vn-uni.shx file into this folder. You may need administrator permissions to perform this action. If the original text was typed using an
The text style configuration is pointing to a missing or corrupted file path.
The most common issue users face is the error when opening a drawing from a colleague or partner. If your system lacks this specific font:
Select "Specify a replacement font" and choose Vn-uni.shx from the dropdown list. To automate this, edit your acad.fmp (Font Mapping File) to map the missing font to an available local font file. Symptom 3: Encoding Mismatch (Text Looks Like Nguyê?n )
While modern versions of AutoCAD have vastly improved their handling of TrueType fonts, Vn-uni.shx remains a staple in Vietnamese design offices. Many "legacy" projects—those started a decade or more ago—still use this font, necessitating its continued presence in font libraries to ensure old files open correctly.
