- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Attempting to modify or add text inside a PDF file that was originally created with the Comenia Sans font.
- Observed behavior
- The PDF editor replaces Comenia Sans with an alternative system font because the original font is not installed on the local computer.
Verify that you have the legitimate font file (usually in .ttf or .otf format) for Comenia Sans saved on your local hard drive before applying the fix.
Install the Comenia Sans Font on Your Computer
Installing the missing font directly to your operating system allows Acrobat and other PDF editors to access and use it during text editing.
PDF editors rely on the fonts installed on your local computer to type or edit text. Even if a font is embedded in the document for viewing purposes, it must be fully installed in your system library for the editor to use it when modifying the text. If it is missing, the software will automatically substitute it with a default font.
Purchase or download the licensed Comenia Sans font file from a reputable typography source.
Right-click the downloaded .ttf or .otf font file and select 'Install' or 'Install for all users'.
Double-click the font file to open the Font Book preview window, then click the 'Install Font' button.
Close Adobe Acrobat completely, then reopen your document to start editing with the newly installed font.

Frequently Asked Questions
Why does Adobe Acrobat change fonts when I start typing?
Acrobat substitutes fonts if the original font used to create the document is not installed locally on your current device. Even if a font is embedded for viewing, it must be installed on your operating system to be used for active text editing.
Can I edit a PDF if I don't have the original font installed?
Yes, but the PDF editor will automatically replace the missing font with a default system font (such as Arial or Minion Pro). This will change the formatting and visual appearance of your text.
Where can I get the Comenia Sans font?
Comenia Sans is a commercial typeface. You will need to purchase a valid license and download the font files from an authorized font distributor or the original typography foundry.
