How to check if a font contains the required glyphs for Word to PDF and image conversion?

It is essential to verify whether the used font in the input Word document supports the required glyphs, particularly when working with different languages or special characters. If a font does not include specific glyphs, Microsoft Word will automatically replace them with a fallback font, potentially leading to inconsistencies in document formatting. This article provides a simple method to check font glyph support using Microsoft Word.

Steps to check if a font contains the required glyphs:

1. Find the suspected font in a Word document

• Open the document in Microsoft Word.
• Remove all unnecessary content, keeping only the text that uses the suspected font.
  
  

2. Save the document as a PDF

• Click File > Save As.
• Choose PDF as the file format.
• Click Save to generate the PDF.

3. Check the embedded fonts in Adobe Acrobat

• Open the saved PDF file in Adobe Acrobat Reader.
• Press Ctrl + D to open the Document Properties window.
• Navigate to the Fonts tab.
• Review the listed fonts.
  
  

4. Analyze the Results

• If the expected font appears in the list → It contains the required glyphs.
• If a different font is listed → The original font does not support the glyphs, and Microsoft Word has used a fallback font.

Similarly, when converting a Word document to PDF using DocIO, if the selected font does not contain the required glyphs, the text may not be rendered correctly in the converted PDF. This can result in missing characters or incorrect formatting. To ensure the text appears correctly in the output PDF, a fallback font must be specified to substitute the missing glyphs.

For detailed steps on using fallback fonts during Word-to-PDF conversion with DocIO, refer to the documentation.
