#HOW TO CHECK FONT EMBEDDING IN PDF PDF#
This is because PDF is a universal format designed to be displayed on any computer running any operating system. Why CID font embedding existsĪlthough Help+Manual can generate PDFs from projects written in Unicode-based languages, the Adobe PDF format does not actually support Unicode directly. Otherwise you will get oversized PDFs or incorrect rendering or both.

The only way to really get all characters to render correctly is to use fonts that really contain all the characters you are using.

If special characters are not rendering correctly this is also a sign that the font you are using does not contain all the necessary characters, and Windows font substitution is also failing to find them. This also means that these fonts will not actually be used even if CID is off: Then, Windows will perform font substitution and will replace your font with one that does contain the necessary characters.

If your PDF files get massively larger with CID embedding switched on, that is a sure sign that the fonts you are using do not contain all the characters you need. We can only suggest that you test your PDFs with CID on and off to see which is better for your specific needs. It is not really possible to provide more than a general rule of thumb for CID font embedding: It should usually be off for Asian languages, Russian and Greek, but it can provide better rendering and smaller PDF sizes for other languages. Type 3 embedding will usually produce the best results for such documents, even if you are not using Type 3 fonts in your project (Help+Manual embeds the fonts in Type 3 mode.) Recommendations for CID font embedding In most cases, it is better to choose either TrueType or Type 3 embedding for Asian documents, particularly Asian documents that also contain text using the English alphabet. This is because the characters are then rendered as glyphs (small graphics). When you select CID font embedding for Asian fonts the PDF will generally look very good but you will usually not be able to select or search the text and the PDF file will be very large.

Also, it will not be possible to select or copy text from the PDF, because it does not contain text, only graphics.Įffectively, this means that Embed CID Fonts only works with Unicode fonts that contain the full Unicode character set! CID font embedding and Asian fonts The text will automatically be rendered as graphical glyphs because the characters are not available, which will make your PDF files huge. If you select a normal western font like Trebuchet that does not contain the characters for the language you are using you will have problems. This only works with fonts that actually contain all the characters you need to display. When you activate Embed CID Fonts the characters actually used in the project are embedded in the PDF file as "virtual" fonts, using a special internal format and CID (Character ID) encoding of the characters. The Embed CID Fonts option in Configuration > Publishing Options > Adobe PDF > Font Embedding is a rather esoteric technology that can reduce the size of your PDF and improve font rendering.
