While Unicode supports the vast majority of use cases, there are certain specialized niches which require characters and glyphs not (yet) represented in the standard. Thus the Private Use Area (PUA) at code points E000–F8FF, which enables third parties to define arbitrary character sets. This package allows configuring a number of macros for using various PUA character sets in LaTeX (AGL, CYFI, MUFI, SIL, TITUS, UCSUR, UNZ), to enable transcription and display of medieval and other documents.
