	This file implements the collating sequence for Windows-1250
	character set. It merely extends the binary sorting of US-ASCII
	by adding characters with diacritical marks into proper places.
	In addition, it sorts 'ch' between 'h' and 'i', and the sorting
	is case sensitive, with uppercase being sorted first, in the
	second pass.

	Bug reports and suggestions are always welcome.
