-commit 4c8316f9cfda38d75fb015c0eb40e0eebb03d28f

- 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).
