Convert old documents to Unicode

Before Unicode, Tibetan was typed with special fonts that put Tibetan shapes where Latin letters normally sit. Open such a document without the font and you see random English or symbols; even with the font installed, the text cannot be searched or moved to another program.

Converters read those old documents and give you proper Unicode Tibetan. They are matched to particular fonts, so check the result against the original.
