If you are trying to copy text from a PDF with a corrupted ToUnicode CIDFont table and getting random symbols, the text layer is permanently broken. You must treat the PDF as an image and extract the text visually.

When a program (often an older or poorly configured one) creates a PDF, it sometimes fails to fully embed the fonts it uses. The resulting PDF still contains instructions on how to display the text, but it cannot tell your computer the original font's name. As a fallback, the software assigns a generic, internal placeholder name to this missing font data, often following a pattern like CIDFont+F1 , CIDFont+F2 , and so on. The F1 , F2 , etc., are often used by the software to distinguish between different font styles or weights it has substituted within the same document, such as regular, bold, or italic variants.

If you have ever opened a PDF document and encountered missing text, strange symbols, or error messages mentioning , you are not alone. These alphanumeric codes are not actual commercial font names like Arial or Times New Roman. Instead, they are internal postscript font aliases used by PDF creation software.

They indicate that the PDF relies on an external font pack or font embedding that your system cannot currently read. Why Do You See the CIDFont Error?

The CIDFont F1–F4 error occurs when a creator , and your PDF reader does not have the corresponding font package installed on your system.
