# Embedded Fonts - PDF

Text in PDF files sometimes contains embedded fonts. If you experience difficulties filtering embedded fonts, you can skip this type of text.

NOTE: If you skip embedded fonts, none of the content that contains embedded fonts is included in the output.

To skip text that uses embedded fonts

- In the C++ API, invoke `skip_embedded_fonts(true)` on a `Configuration` object. See The Configuration Class and skip_embedded_fonts for more information.

## Use the formats.ini File

When you use `formats.ini` to skip embedded fonts, you can also specify an embedded font threshold, which is an arbitrary percentage probability that the glyph in the embedded text maps to a character value in the output character set (ASCII, UTF-8, and so on).

For example, if you specify a threshold of `75`, embedded text glyphs that have a 75% or greater probability of correctly matching the character in the output character set are included in the output; glyphs that have a probability of less than 75% of matching the output character set are omitted from the output.

To skip embedded fonts by using the formats.ini file

- Set the following parameters:

      [pdf_flags]
      skipembeddedfont=TRUE
      embedded_font_threshold=threshold

  where `threshold` is a value between `0` and `100`. A threshold of `100` skips all embedded font text; a threshold of `0` retains all embedded font text.

  The default value of `embedded_font_threshold` is `100`. if you set `skipembeddedfont` to `TRUE` and do not specify the `embedded_font_threshold` parameter, Filter skips all embedded text.
