Re: [PHP-DB] Input ++90 causing problems From: graeme (graeme_foster <email protected>)

Hi,

I was able to trick IE but not Firefox to display some of the characters
you had displayed.
ﯝ ﯝ212-

By selecting the encoding Arabic ASMO 708 and then selecting auto select
in the encoding. On IE with right to left it appears -212 followed by
the two characters that look like a sleepy 9 with a u on top.

I suspect that it is an issue with the encoding. Have you tried to state
the encoding to use in your HTML?
