Other Unicode characters and symbols

Unicode symbols can be entered in decimal form, like this:

p{font-size:20pt;}. ☢ ☁ ♘

With a browser that is capable, and a font that supports the characters, you will see this:

Conversion of hexadecimal representation of Unicode symbols

For searching and conversion of Unicode symbols into their HTML form, see the Unicode character table tool.

Setting alternate glyphs

Textile’s typographic substitutions can be overridden with the setSymbol method. If you need to set up Textile to do non-standard substitutions, call setSymbol before you parse the input with textileThis or textileRestricted.

$parser = new \Netcarver\Textile\Parser();
$parser->setSymbol('half', '1⁄2');
$parser->textileThis('Hello [1/2] World!');

The symbol names you can pass to setSymbol() can be found here.
