-------------------------------------------------------------------

It turned out that there is a way to reproduce the problem with some non-exotic 
code. The tilde mentioned isn't the tilde from the keyboard. In this code, the 
first one is "asciitilde" (keyboard) and the second is "tilde":
{code}
showText("~˜");
{code}
And this also reproduces the effect.

(Firefox shows only one, MSIE shows both)
