Need to remove empty square symbol from text

Copy linkTweet thisAlerts:

I have been looking for days for a way to do this but have made no progress.

The text looks fine in php but when displayed by javascript, some of the spaces are shown as an empty square symbol.

I have tried the following to change any unusual character to a space, but it doesn’t help.

for (ji=0;ji<32;ji++) {
bb=bb.replace(/String.fromCharCode(ji)/g, ” “);
}

for (ji=91;ji<256;ji++) {
bb=bb.replace(/String.fromCharCode(ji)/g, ” “);
}

I believe that the character is created by a javascript-based editor when either the delete or backspace key is used to make an edit.

I have this strange symbol in many articles so I need a way to deal with this (the articles display fine when displayed by a php CMS).
I’m using javascript to show a preview of the article as a link tooltip.

Any help would be greatly appreciated.

@Declan1991Apr 19.2010 — Well that's not a valid RegExp.for (ji=0;ji&lt;32;ji++) {
bb=bb.replace(String.fromCharCode(ji), " ");
}

for (ji=91;ji&lt;256;ji++) {
bb=bb.replace(String.fromCharCode(ji), " ");
}But you can pass strings to replace. An other possibility would be new RegExp(String.fromCharCode(ji),"gi");

Maybe the problem is not a single character ??

Maybe you're right, changed as you suggested and it does replace chars now, but i still see the empty square symbol instead of a space ?

Hover mouse over the hot-air balloon image and the tooltip shows a small square where a space should be. The text is retrieved by ajax from a php script. The php shows no sqaure, just the correct space.

where 550 is the article id.

Something about use of rubout. The square appears when have rubbout text.
