+commit 4c8316f9cfda38d75fb015c0eb40e0eebb03d28f
+Author: Jehan <jehan@girinstud.io>

+
+ 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).
