Aren't there glyphs in Acrobat Pro?

To augment, the response from Bernd Alheit, PDF is a final form file format, not a document format that maintains context of the contents such as articles, columns, words, paragraphs, sentences, and words. The “editing” capabilities of Acrobat are meant primarily for “text touch-up” or minor corrections, not for document composition. As such, most of the tools you would expect in a full-blown document editor are not provided in Acrobat. If you need to access special characters within Acrobat, you could use operating system utilities such as Character Map in Windows (or comparable software on MacOS) to input characters not available from the keyboard.

Acrobat is not an editor, like Word, InDesign
