Jehan 4c8316f9cf Nearly-ASCII text with NBSP is still not ASCII. 
There is no "exception" in encoding. The non-breaking space 0xA0 is not
ASCII, and therefore returning "ASCII" will later create issues (for
instance trying to re-encode with iconv produces an error).
This was obviously an explicit decision in original code (according to
code comments), probably tied to specifity of the original program from
Mozilla. Now we want strict detection.
I will return "ISO-8859-1" for "nearly-ASCII texts with NBSP as only
exception" (note that I could have returned any ISO-8859 charsets since
they all have this character in common).

uchardet

uchardet is an encoding detector library, which takes a sequence of bytes in an unknown character encoding without any additional information, and attempts to determine the encoding of the text. Returned encoding names are iconv-compatible.

uchardet started as a C language binding of the original C++ implementation of the universal charset detection library by Mozilla. It can now detect more charsets, and more reliably than the original implementation.

The original code of universalchardet is available at http://lxr.mozilla.org/seamonkey/source/extensions/universalchardet/

Techniques used by universalchardet are described at http://www.mozilla.org/projects/intl/UniversalCharsetDetection.html
