Question for Sony Ericsson users: charset?

A Sony Ericsson K800 user reported a problem with non-standard
characters (German umlauts in his case). It turned out that the phone
uses ISO-8859-1 instead UTF-8 as encoding, without announcing that.

It is possible to configure the Synthesis engine so that it does with
the character set conversion correctly, but that leads to this
question: which phones need this special treatment?

I’m currently inclined to enable this for all Sony Ericsson phones,
unconditionally. If you are using a Sony Ericsson a) which uses
something else than ISO-8859-1 as local charset and/or b) which works
correctly with non-standard characters already in SyncEvolution 1.1.1,
then please leave a comment.
