I had some problems producing proper Swedish characters in WordPress for a
little while. This only happened when using Mozex and
Vim to edit posts.
The solution was quite simple I use UTF-8 encoding throughout my entire
Ubuntu GNU/Linux system, every application defaults to it. Except Firefox, it
seems. Making sure that the Character Encoding was set to UTF-8 solved it.
I simply can’t stand editing text in the text areas using the editor in
Firefox (Mozilla). Apparently there is still no edit externally command in
Mozilla yet. Luckily there’s Mozex, but don’t try installing that
version, use this instead (the original won’t install anymore). The
original site is still useful though, since it holds a link to the
arguments the different commands take.
