↴ (UTF-8 character 21B4)
This works OK in FF and Op (with/without a UTF-8 meta tag), but IE6 baulks and just displays a square block, regardless of whether there is a UTF-8 meta tag or not. To get it to work in IE6 you need to tell it to use a unicode font!

Specifying symbolic fonts in several cases...
|✓||Check Mark||(not specified)||✓||Firefox 3 displays this character even without the Arial Unicode MS font installed. IE8, Chrome and Safari do not. However, with Arial Unicode MS then IE8/Vista displays this character as well.|
|✓||Check Mark||(not specified)||(copy/pasted - must be from a unicode font?!)|
|P||Check Mark||Wingdings 21||P|
|a||Check Mark (?)||Webdings1||a|
|↭||Left Right Wave Arrow||Cambria Math||↭||Why the large top/bottom margins in FF?|
|ﬄ||Latin Small Ligature Ffl||Cambria (although not specified)|

1 Symbolic (non unicode) fonts are only displayed in Internet Explorer, Chrome and Safari. In Firefox and Opera a font substitute is used instead. Although the reference document does state that the Symbol font works in Opera - this must have been pre Opera 10, since 10.63 this does not work. Ref: Common fonts to all versions of Windows & Mac equivalents
2 "Cambria Math" (unicode font) does not appear to be considered 'symbolic'. It does contain the normal alphabet.
