libuninum is a library for converting Unicode strings to numbers. Internal computation is done using arbitrary precision arithmetic, so there is no limit on the size of the integer that can be converted. The value is returned as an ASCII decimal string, a GNU MP object, or an unsigned long integer. Auto-detection of the number system is provided. The number systems supported include Arabic, Armenian, Balinese, Bengali, Burmese, Chinese, Cyrillic, Devanagari, Egyptian, Ethiopic, Glagolitic, Greek, Gujarati, Gurmukhi, Hebrew, Kannada, Khmer, Klingon, Lao, Limbu, Malayalam, Mongolian, New Tai Lue, Nko, Old Italic, Old Persian, Oriya, Osmanya, Perso-Arabic, Phoenician, Roman Numerals, Tamil, Telugu, Tengwar, Thai, and Tibetan.
The library is available as 32-bit and 64-bit:
