The page displays Unicode characters, which are organised in blocks of 256 character, in pages of 100 characters each, thereby completly hiding the logical structure of Unicode. This is an, let's say, interesting choice...<p>[edit: typo]
Some suggestions:<p>* reduce the height of the character grid by 2 rows - it is too much to fit the whole table on a 1280x1024 which means you have to scroll to see all the characters<p>* change the list of somewhat arbitrary shortcut links on the upper right to an autocomplete field for Unicode block names (<a href="http://unicode.org/Public/UNIDATA/Blocks.txt" rel="nofollow">http://unicode.org/Public/UNIDATA/Blocks.txt</a>)
I really hope it can add some UniHan reference<p><a href="http://www.unicode.org/cgi-bin/GetUnihanData.pl?codepoint=%E4%B9%85" rel="nofollow">http://www.unicode.org/cgi-bin/GetUnihanData.pl?codepoint=%E...</a><p>btw, I really the code point navigation slide bar, it's very intuitive and easy to use.
