New submission from flying sheep:
See also #6331.
The repo https://github.com/nagisa/unicodeblocks contains pretty much the functionality i’d like to see: a way to get access to information about all blocks, and a way to get the block name a char is in.
I propose to include something very similar to those two APIs in unicodedata:
unicodedata.Block: class with start, end, and name property.
its __contains__ should work for single-char-strings (which tests if that char is in the block) and for ints (which tests if the codepoint is in the block)
maybe make it iterable over its chars?
unicodedata.blocks: OrderedDict of str (block name) → Block object mappings ordered by Block.start.
then blocks.keys() would yield the names in order, and blocks.values() the block objects in order.
unicodedata.block_of(chr, name_only=False): returns the Block object for which “chr in block” is True, or its name.
---
alternative: make the Block class an unfancy namedtuple without __contains__ method.
---
Together with #18234, fixing this bug will complete UnicodeData support in python, i guess.
