Inspect a TrueType or OpenType font

Use jetformat font info to inspect a TrueType or OpenType font.

By Jetformat

Read font summary, table information, and character mappings when diagnosing missing glyphs. A family name alone does not prove that every required character exists.

Steps

  1. Start with a local TTF or OTF font. Replace the sample paths and identifiers with your own.
  2. Run the command below. Read the returned data before choosing a follow-up edit.
  3. Check the result as described below before using it in another job.
jetformat font info font.ttf

Notes and limits

This is a free utility or read operation. It does not need a paid conversion to inspect the result.

Run jetformat font info --help to compare options with your installed version.

See the font command reference for the surrounding workflow.
