I have a problems with search streets and adresses on my device in gmapsupp.img when i make it with --code-page=1251.

I have:
openSUSE 12.3 x64, java-1_7_0-openjdk, Garmin Dakota 20.

My options for mkgmap:
--style-file=default
--gmapsupp
--bounds=world-boundarys
--route
--index
--add-pois-to-areas
--tdbfile
--lower-case
--drive-on-right
--code-page=1251
-c splitted/template.args default/openstreetmap.TYP

I have no problem when I specify the option - code-page = 1252
Many streets in search not available when I specify the option - code-page = 1251

I tried the version r2659 r2656 r2654 r2653 r2648 r2643. Everywhere there is this problem. I do not have older versions.
