Remove strange text from POST form?

[kosmosinga]

Hello, everyone! Can anyone tell me how to remove the strange characters for example with a $text parameter that writes to the database and then returns that text with the database.
This is text of this type, perhaps generated with a font. Anyone know how to get rid of this?

and more...

Thank you.

Where is the code that produces this?

I think I found a solution with iconv, but in this case the emojis (like 😋) don't work. Does anyone have any idea how to fix this?

$text = iconv("UTF-8", "ASCII//TRANSLIT//IGNORE", $text2);

Why is it a problem? If that's what the user entered then you should be showing it back to them...

[kosmosinga]

The problem is that emojis don't work with iconv.
At this point ŝ̬ô̬m̬̂ê̬t̬̂ê̬x̬̂t̬̂ is fine and converts the text to normal, but when I post an emoji it just doesn't work.

[requinix]

No, no, I mean what's the problem with allowing text like ŝ̬ô̬m̬̂ê̬t̬̂ê̬x̬̂t̬̂? The forum's own software is doing it right now.

If you want to pick and choose which characters can be used, you'll have to go through the unicode character list, decide what you do and don't want, then probably write your own filtering code for that.

I dunno about you, but to me that seems like a lot of work for very little or no benefit.
