Weird problem comparing Hebrew characters

[IlanMS]

Letter duos צ/ץ, מ/ם, נ/ן, כ/ך yield wrong TRUE/FALSE values when compared. Look at the code.

The duos do have meaning, but that's beside the point. I get wrong values half of the time. I tried to change the script encoding to UTF8, ANSI, UTF-BOM, still fail.

$c = "צ"
if $c = 'ץ' then
    MsgBox (0, "ץ", $c)
else
    MsgBox (0, "צ", $c)
EndIf
;Wrong

$c = "ץ"
if $c = 'ץ' then
    MsgBox (0, "ץ", $c)
else
    MsgBox (0, "צ", $c)
EndIf
;Right
if $c = 'צ' then
    MsgBox (0, "צ", $c)
else
    MsgBox (0, "ץ", $c)
EndIf
;Wrong again. The 1st comparison always generate TRUE regardless of letter from the duo צ/ץ
;Same problem with -  מ/ם, נ/ן, כ/ך

Adding encoding attempts

I am not sure exactly why but it may work better if you use if $c == 'ץ' in your expression.

Double equals "==" is used for case sensitive comparisons and may be required here.
