Remove ancient README.translators

Yo, listen up, here’s a story
About a little guy that lives in a UTF-8 world
And all day and all night and everything he sees
Is just UTF-8 like him inside and outside
UTF-8 his house with a UTF-8 little window
And a UTF-8 corvette
And everything is UTF-8 for him and himself
And everybody around
’Cause he ain’t got nobody to listen

-All the .po files are now in UTF-8!
-
-For information on editing UTF-8 files on Unix, see
-<http://www.cl.cam.ac.uk/~mgk25/unicode.html>
-
-If you just want to convert it back to your native encoding to
-edit and then convert again to UTF-8 to commit, please see the
-scripts in gnome-i18n/UTF-8, for example
-
-  export ENCODING_TO=ISO-8859-15
-  utftopo fi.po
-  emacs fi.po
-  potoutf.sh fi.po
-  cvs commit fi.po
-
-Alternatively, you can use the gettext package (>= 0.11) to convert
-your translation to and from your native encoding:
-
-msgconv -t ISO-8859-15 fi.po > fi.native.po
-emacs fi.native.po
-msgconv -t UTF-8 fi.native.po > fi.po
-cvs commit fi.po
-
-If you need help with this, ask, but please don't commit
-non-UTF-8 files here.
