Comment(by Denis-de-Bernardy):

 11219.3.diff works too, and it should be applied to WP 2.9.1.

 In 1.1.3, the encoding() function returns Windows-1252, whereas 1.2
 returns windows-1252 (lowercase), when the input is ISO-8859-1. The patch
 fixes the check in change_encoding() accordingly.

 I think we should also consider applying Ryan's patch, or something
 similar, in WP 3.0. In order to handle UTF-8 to UTF-8 "conversion" in a
 secure manner.
