Unicode Blocks (3.1)


The Unicode charset consists of a number of blocks of characters. What the blocks are is defined by the Unicode Consortium, and you can find this definition in the file Blocks.txt.

Among those blocks, there are some which I personally don't think are safe. I on this page have marked those with "No" in first column. Note that it is for deployment easy to add blocks later on, but not possible to delete blocks after they have been introduced.

Safe?
