Representing Blocks.txt?

[faassen]

I dug around the source code, but I couldn't find a representation in Rust code of the Blocks.txt data. There's the unicode_blocks crate, but this misses an important feature; I need to be able to iterate through all blocks. I need to be able to look them up by name, but not the name as given as this has space characters. So iteration seems required so I can do some pre-processing. This is to implement regular expressions as defined by appendix F in the XML Schema specification:

Being able to get a CodePointInvList for a block would also be nice.

Did I miss something? Is this planned?

Good suggestion! I opened #4803. This would be a good first issue if someone wanted to contribute this.
