Speaking of Unicode, as I did yesterday, Xah Lee has updated and rearranged all his pages dealing with Unicode and added a single, unified Unicode Gallery & Tutorial index page. I really like this because it provides a single page that serves as a portal to a vast amount of information about Unicode.
If, like me, you don’t use the rarer Unicode symbols everyday, this is a good resource to bookmark. If you are an Emacs user who often needs specialized Unicode characters, Lee lists some tools that may help. Regardless, it’s worth looking at the page just to see what’s there in case you need it later.
