As a work-around, I've submitted to CRAN a revised version of spgrass6 
allowing the user to manipulate the encoding string in the XML data 
directly, since Windows users of binary releases cannot get at this 
themselves on the GRASS side.

The user would typically run a parseGRASS(<whatever>) command, see a UTF-8 
error message, and then try inserting usual suspects with setXMLencoding() 
- typically "latin1" - and retry parseGRASS(<whatever>). Users of 
initGRASS() will see the UTF-8 error because parseGRASS("g.region") is run 
when the function completes.
