The true power of CID fonts lies in their structure. A standard font might support 256 characters. A CID font supports 16-bit values, giving it the theoretical ability to index up to 65,535 separate characters. Technically speaking, a CID-keyed font can be seen as a collection of several "sub-fonts" combined into one large file. One section might contain all the Latin letters, another all the Japanese Hiragana syllables, and a third the thousands of Kanji characters.
| CID Label | Typical Role | Free Font Download | |-----------|--------------|--------------------| | | Japanese sans‑serif | Noto Sans CJK JP – Google Noto | | F2 | Japanese serif | Noto Serif CJK JP – Google Noto | | F3 | Korean sans‑serif | Noto Sans CJK KR – Google Noto | | F4 | Korean serif | Noto Serif CJK KR – Google Noto | | F5 | Chinese Simplified | Noto Sans CJK SC – Google Noto | | F6 | Chinese Traditional | Noto Sans CJK TC – Google Noto | | F7 | Fallback / Mono | Noto Mono or Sarasa Gothic – GitHub (Sarasa) |
If your goal is not to find the CID font, but to get your PDF to work correctly, you have several practical options: When a program can’t find the original font
When a PDF is generated, sometimes the original font's naming information is lost, and the system creates a temporary, encoded subset font to represent it.
Each referenced font gets a local name like /F1 , /F2 , etc., defined in the /Resources dictionary.

CID (Character Identifier) fonts are specialized PostScript fonts designed to handle languages with massive character sets, such as Chinese, Japanese, Korean (CJK), and highly complex technical layouts.
For Linux users or developers using command-line tools like Ghostscript, you can map the placeholders to real fonts manually. You must place the CIDFont files into the Ghostscript resource directory and modify the cidfmap configuration file to map a TrueType font (like Windows' built-in msyh.ttf ) to the CID request.
