How can I post a percent sign via Codeigniter?

[eluser]Unknown[/eluser]
Hello.

I'd tried to create a textarea to post something.
But it doesn't work well with percent sign like "% 1000"(no space between % and 0).
It seems to identify "% 10" as some ASCii character.
And I found that the forum has the same problem.

How can I solve this question? thanks.
and I apologize for my poor English.

PHP.net printf and sprintf

[quote author="InsiteFX" date="1312653301"]PHP.net printf and sprintf[/quote]

I've tried this:

Code:

printf("%s" , $_POST['val']);

but it still doesn't work.
