[GRASS-user] problem with r.li. modules-Charakter Encoding?

Hi all,
I have noted one little problem with r.li. modules, when trying to use
overlayed vector map as sampling areas. As example, r.li.edgedensity writes
back this message:

r.li.patchnum map=r1953_10m@landuse conf=pokus1953 output=pokus1953patchnum

I guess, this can be caused with incorretct character encoding (my current
settings is ISO-8859-2), but no attempt to change it was succesfull (only
the error message changed in other "not allowed charakter"). I tryed UTF-8,
Windows-1250 and others.
The same vector map, used as sampling area as whole map did works. The
vector map contains this columns types:
INTEGER|cat
INTEGER|CISLO
CHARACTER|KULTURA
DOUBLE PRECISION|PLOCHA
DOUBLE PRECISION|NOVA_AREA
INTEGER|landuse
There is no special character, such as š,ě,í,ö,ä in columns

The second problem with r.li modules is, that I cannot calculate any indice
on 1 m resolution raster with any r.li module. The same, 10 m resolution
raster goes great...is 1 m resolution supported by r.li modules?
Thanks for your helpful answers
Martin

I doubt it. It looks as if an error is occurring, and rather than
detecting this and aborting, r.li continues processing but using
garbage data.

Unfortunately, r.li is quite complex, and the fact that it is
implemented as several distributed processes can make debugging
awkward.

r.li is unlikely to care about physical resolution (in metres), but it
may well fail if the total number of cells is too large. This will
impose a limit on the combination of the region size and the
resolution, i.e. you may be able to use 1m resolution on a small
region, but not on a larger region.
