# `Unicode.Block`
[🔗](https://github.com/elixir-unicode/unicode/blob/v1.21.1/lib/unicode/block.ex#L1)

Functions to introspect Unicode
blocks for binaries
(Strings) and codepoints.

# `aliases`

Returns a map of aliases for
Unicode blocks.

An alias is an alternative name
for referring to a block. Aliases
are resolved by the `fetch/1` and
`get/1` functions.

# `assigned`

Returns a list of tuples representing the
assigned ranges of all Unicode code points.

# `block`

Returns the block name(s) for the
given binary or codepoint.

In the case of a codepoint, a single
block name is returned.

For a binary a list of distinct block
names represented by the graphemes in
the binary is returned.

# `blocks`

Returns the map of Unicode
blocks.

The block name is the map
key and a list of codepoint
ranges as tuples as the value.

# `count`

Returns the count of the number of characters
for a given block.

Aliases are resolved by this function.

## Example

    iex> Unicode.Block.count(:old_north_arabian)
    32

# `fetch`

Returns the Unicode ranges for
a given block as a list of
ranges as 2-tuples.

Aliases are resolved by this function.

Returns either `{:ok, range_list}` or
`:error`.

# `get`

Returns the Unicode ranges for
a given block as a list of
ranges as 2-tuples.

Aliases are resolved by this function.

Returns either `range_list` or
`nil`.

# `known_blocks`

Returns a list of known Unicode
block names.

This function does not return the
names of any block aliases.
