• English text in a mixed Tibetan/Latin PDF extracts correctly from the original file, but comes out as Tibetan gibberish from the .patched.pdf produced by pdf-cmap-fix:

Patched   (wrong):    བཌཨཕྱྭཕྱགྲཤཀྱཌསཤཁྲཌཔྱགྱཕྱྭཔྱཊཕྱྭཁྲཌཌཀྲཕྱྭཤཔྱཔྱཎཕྱྭཐྲཤཀྲཕྱྭཁྱཤཧཨཕྱྭ…

• The Tibetan content of the document is unaffected and patches correctly.
