normalise_openid ( $s )

notags ( $string )

This is our primary input filter.

The high bit hack only involved some old IE browser, forget which (IE5/Mac?) that had an XSS attack vector due to stripping the high-bit on an 8-bit character after cleansing, and angle chars with the high bit set could get through as markup.

This is now disabled because it was interfering with some legitimate unicode sequences and hopefully there aren't a lot of those browsers left.

Use this on any text input where angle chars are not valid or permitted They will be replaced with safer brackets. This may be filtered further if these are not allowed either.

Description: Replaces text emoticons with graphical images

Returns string

It is expected that this function will be called using HTML text. We will escape text between HTML pre and code blocks from being processed.

At a higher level, the bbcode [nosmile] tag can be used to prevent this function from being executed by the prepare_text() routine when preparing bbcode source for HTML display
