Hi Harry,

Dunno about the performance penalty, but so far I am happy with LATIN1 dbase
system (RH and Trustix). Even with cyrillic characters. Then again, I work
with browser interfaces and it's not really up to me what encoding the client
has or has not installed. <if western, charset=iso-iso-8859-1, if fellow
russki harasoo charset=windows-1251> is, I guess, a good bet. It's a windows
world, so far.

Soviet KOI-X X, KOI8-r, KOI8-RU, Mac Cyrillic (Standard), CyrWin Cyrillic and
the rest of the soup ...

Some experience and my half a pea.

BR,

Aarni
