+commit 4c8316f9cfda38d75fb015c0eb40e0eebb03d28f
+Author: Jehan <jehan@girinstud.io>
+Date:   Sat Dec 5 21:04:20 2015 +0100
+
+    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).
