Re: Re: [Gramps-users] Problem with RelGraph.py

[<nic...@ne...>]

Hi Alex,

Thanks for the patch --- I tried it and it does fix the problems: the
cyrillic text appears correctly in the .dot file. One remaining issue
for me is that the cyrillic is not rasterized properly by =22dot -Tpng=22
with the FreeSans font which is specified by default. It works with
Arial, though, it this may be something to do with my system. =


So please include the patch -- thanks again for looking into this.
