CIDFont is a shorthand for “Character IDentifier Font,” a font format developed by Adobe Systems to efficiently handle large character sets, particularly for languages like Chinese, Japanese, and Korean that contain thousands of glyphs. Unlike traditional fonts that identify characters by name, CID-keyed fonts use numeric Character IDentifiers (CIDs) to reference individual glyphs, making them more efficient for complex writing systems.

Here's a brief overview of each font format:

In traditional digital fonts, characters are mapped directly to specific keyboard inputs. However, languages with massive character sets—such as Chinese, Japanese, and Korean (CJK)—require tens of thousands of unique glyphs.

The "CID" in CIDFont stands for , and "CIDFont" refers to a composite font mechanism used in PDF and PostScript files. These fonts are commonly used for handling large character sets, such as Chinese, Japanese, and Korean (CJK) fonts, or complex Unicode fonts. The "F1-F6" Mystery

在某些场景下，PDF 生成软件可能会因为字体名称冲突或转换过程中的技术限制，自动为字体生成一个新的名称，从而把原有字体名称替换为类似 CIDFont+F1 的标识。有开发者反馈，从 Microsoft Word 转存 PDF 时，原本正常的文档会自动生成从 CIDFont+F1 到 F5 等多个占位符。

When the underlying character map of a PDF is completely destroyed, OCR tools can rebuild it from scratch.

On older macOS systems (Classic OS 9 or early OS X), data fork fonts (DFONT) sometimes exposed internal resources as f1 , f2 , etc. A corrupt DFONT containing CID resources might list its suite as:

The most frequent cause is that the author of the PDF did not embed the fonts into the document. If a font is not embedded, your PDF reader tries to find that exact font on your local device. If your computer lacks that specific CJK or specialized font pack, the reader fails to render the text and falls back on the internal CID code names. 2.
