PL/Tcl appears to contain logic to convert strings between the database encoding and UTF8, which is the only encoding modern Tcl will deal with. However, that code has been disabled since commit 034895125d648b86, which made it "#if defined(UNICODE_CONVERSION)" and neglected to provide any way for that symbol to become defined. That might have been all right back in 2001, but these days we take a dim view of allowing strings with incorrect encoding into the database. Remove the conditional compilation, fix warnings about signed/unsigned char conversions, clean up assorted places that didn't bother with conversions. (Notably, there were lots of assumptions that database table and field names didn't need conversion...) Add a regression test based on plpython_unicode. It's not terribly thorough, but better than no test at all.
