[R] metafor package: changing decimal in forest plot to midline decimal

Thanks for that link, Wolfgang. Unfortunately, there comes the Warning 
with it:
"(process:3634): Pango-WARNING **: Invalid UTF-8 string passed to 
and decimal being "scrambled" in forest plot and not displaying the 
midline decimal.

I think it has to do with the fact, that only 1-byte-codes are allowed 
for options(OutDec="\xB7").
Or does it have to do with me using Ubuntu?

Apart from that the options-command does not seem to change the decimal 
of values on the "true" x-axis under the plot.

Still searching for a solution.
