* library/demos/unicodeout.tcl: Added code to check for
right-to-left support on Windows and adjust Hebrew and Arabic
character strings accordingly. Changed the Hebrew string to
'ktb ebryt' (ktav Ivrit, "Hebrew writing") to be consistent
with at least the Greek and Russian strings. Thanks to
Rodrigo Readi for calling the inconsistency to our attention.
