dia 0.97.1 does not accepts argument with iso8859-2 via command line

[Kaminar <Kaminar seznam cz>]

Hello,

I have set locales to cs_CZ.ISO8859-2 on FreeBSD 8.1 and I use
ISO8859-2 characters in my file names.
I use converting dia diagram to EPS format via command line.
But from version dia 0.97.1 when I convert diagrams to EPS,
dia gets error message and nothing converts:

$ dia -t eps filename-with-iso8859-2-characters.dia
Missing input: filename-with-iso8859-2-characters.dia

In previous versions of dia (e.g. 0.97) everithing goes fine.

Converting dia files from CLI is very important for me,
because I use it in makefiles.

Is there any solutions to this problem?
