- Product
- Word / Acrobat PDF Maker
- Device & OS
- not provided
- Scenario
- Converting a Word document containing custom fonts into a PDF file for submission or printing.
- Observed behavior
- Special characters and font glyphs are replaced by blank boxes (often called tofu) in the resulting PDF because the original font was not embedded.
Ensure that the custom fonts (such as the Bach music font) are fully installed on your local computer and that their licensing permits document embedding.
Embed All Fonts Using Acrobat PDF Maker Preferences
Configure your PDF export settings in Microsoft Word to embed all fonts, ensuring custom glyphs display properly.
When a custom font isn't embedded, PDF viewers substitute it with a default font that may lack specific characters. Using the Acrobat add-in preferences guarantees all necessary font data is included.
Launch Microsoft Word and open the source document containing the music fonts.
Navigate to the Acrobat Ribbon (or PDF Maker tab) at the top of the Word window.
Click on 'Preferences' or 'Conversion Preferences' from the toolbar menu.
Locate the font settings within the preferences dialog and check the option to 'Embed all fonts'.
Click the 'Create PDF' button to export your document with all font glyphs securely embedded.

Use Microsoft Word's Native Save As PDF Feature
If you do not have the Acrobat plug-in installed, you can use Word's built-in PDF export options to embed fonts.
Use WPS Office to Export Documents with Embedded Fonts
WPS Office provides a robust, built-in PDF converter that ensures high-fidelity output. It easily handles custom fonts, complex layouts, and special glyphs like music notation, making sure your PDFs look exactly like the original.
- 1. Open your Document: Open the source document containing the custom music fonts in WPS Writer.
- 2. Access Export Menu: Go to the 'Menu' in the top left corner and click on 'Export to PDF'.
- 3. Open Advanced Settings: Click on the 'Advanced' or 'Settings' button within the export dialog box.
- 4. Select Font Embedding: Ensure that the option to embed fonts is selected to preserve your custom glyphs.
- 5. Export the File: Click 'Export' to generate a flawless PDF with all musical notation intact.

Frequently Asked Questions
Why do custom fonts turn into blank boxes in my PDF?
Blank boxes, often referred to as 'tofu', appear when a custom font is not embedded in the PDF. The PDF viewer substitutes the missing font with a default system font that lacks those specific glyphs.
How do I know if my font allows embedding?
You can check font embedding permissions by right-clicking the font file (.ttf or .otf) in your system's font folder, selecting Properties, and looking at the Details or License tab for embedding rights.
Can I fix the PDF without the original Word document?
If the fonts weren't embedded during the original conversion, you generally need the source file and the locally installed fonts to recreate the PDF properly. Editing the PDF directly to fix missing glyphs is difficult without the source.
Does WPS Office support custom music fonts?
Yes, WPS Office supports any TrueType or OpenType font installed on your system. It can seamlessly embed these custom fonts when exporting to PDF to maintain exact visual fidelity.
