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.
