Importing text files with umlauts and sharp-s's

[Alexandra Walford <chroma delusion de>]

Hello,

I'd like to use Gnumeric to import some basic tab-delimited text files,
many of which contain umlauts and sharp-s's.  When I try to import
these files I am told that "This file does not seem to be a valid text
file.  The character ü (ASCII decimal 252) was encountered.  Most likely
your locale settings are wrong.".  Does this mean that although I am an
English speaker living in an English speaking country (Australia), I
cannot import files with such characters unless I start fiddling with
locale settings?  Could someone give me advice on the best way to get
around this?

Thanks very much; Gnumeric is looking like a very polished app.

user-oriented list anywhere?)
