In some implementations, a computer system for obfuscating text in an electronic document can include an analysis module, a font data repository, a re-coding module, and a data interface. The analysis module is operable to identify strings of text from an electronic document. The font data repository can include one or more character maps that correlate, for each character map in the one or more character maps, a first set of characters with a respective different second set of characters. The re-coding module can generate a re-coded document by re-mapping, using a particular one of the one or more character maps, the identified strings of text into corresponding obfuscated strings of text, and by replacing the identified strings of text with the corresponding obfuscated strings of text from the electronic document. The data interface can transmit the re-coded document to a client computing device.
