No, it's a problem in transmission.  The actual patch is a mixture of 
UTF-8 and Latin-1 encoding.  I sent it via Thunderbird, which doesn't 
know its encoding and says only "Content-Type: text/x-patch" without 
specifying a character set for the attachment.  The body of the 
attachment, generated by Git, says "Content-Type: text/plain; 
charset=UTF-8" which is not correct, as the attachment body uses some 
UTF-8 and some Latin-1.

If I save the attachment into a file FOO, and edit FOO with Emacs, Emacs 
ignores the charset declaration and infers Latin-1 since FOO can't 
possibly be UTF-8, which botches display of the UTF-characters (the 
botch you noticed).  If I then type 'C-x RET r U T F - 8 RET y e s RET', 
Emacs will show the patch as UTF-8 instead of Latin-1, which will fix 
the botch you noticed but will mess up display of the old contents of 
locale.aliases.

What a mess, huh?

Sure, revised patch attached.  It'll have the same transmission problems 
as before, and if you force Emacs to read it in UTF-8 only the old lines 
will be botched.

Subject: [PATCH] Remove obsolete aliases that broke 'locale -a'
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

[BZ #18412]
* intl/locale.alias: Remove obsolete aliases "bokmål" and "français"
which caused 'locale -a' to output Latin-1 data in UTF-8 locales,
breaking some applications that use 'locale -a' output.
Change the encoding of this file from Latin-1 to UTF-8
(this affects only the file's comments now).
