Unicode Character Equivalence Support in Web Browsers

It's very nice, in Google Chrome and Safari, that if you type 3 dots ... in the find box 【Ctrl+f】, it'll find the Unicode character ellipsis …. Here's some other equivalences:

• e ⟺ é
• a ⟺ à
• i ⟺ î
• n ⟺ ñ
• u ⟺ ü
• others accented letters ⁖ ÀÁÂÃÄÅÆ Ç ÈÉÊË ÌÍÎÏ ÐÑ ÒÓÔÕÖ ØÙÚÛÜÝÞß àáâãäåæç èéêë ìíîï ðñòóôõö øùúûüýþÿ
• "straight double quote" ⟺ “curly double quote”
• 1 ⟺ ①
• 2 ⟺ ②
• 3 ⟺ ③
• ... ⟺ …
• any char is equivalent to its fullwidth version. ⁖ () [] {} vs （） ［］ ｛｝, and fullwidth forms of punctuations “, . ; ? !” etc. 〔☛ Unicode Full-Width Characters〕

I think some of these are based on Unicode equivalence but not all.

Note: Firefox, Opera, does not support this. It's funny that IE8 support some of them. If you type “1”, it'll find “①”, but if you type “e”, it won't find “é”. (all browsers tested are latest public versions as of 2011-03-09.) You can test by 【Ctrl+f】 right on this page.
