wezterm/bidi/data/BidiBrackets.txt
Wez Furlong 601a85e12b Add wezterm-bidi crate 
In order to support RTL/BIDI, wezterm needs a bidi implementation.  I
don't think a well-conforming rust implementation exists today; what I
found were implementations that didn't pass 100% of the conformance
tests.

So I decided to port "bidiref", the reference implementation of the UBA
described in http://unicode.org/reports/tr9/ to Rust.

This implementation focuses on conformance: no special measures have
been taken to optimize it so far, with my focus having been to ensure
that all of the approx 780,000 test cases in the unicode data for
unicode 14 pass.  Having the tests passing 100% allows for making
performance improvements with confidence in the future.

The API isn't completely designed/fully baked.  Until I get to hooking
it up to wezterm's shaper, I'm not 100% sure exactly what I'll need.
There's a good discussion on API in
https://github.com/open-i18n/rust-unic/issues/273 that suggests omitting
"legacy" operations such as reordering. I suspect that wezterm may
actually need that function to support monospace text layout in some
terminal scenarios, but regardless: reordering is part of the
conformance test suite so it remains a part of the API.

That said: the API does model the major operations as separate
phases, so you should be able to pay for just what you use:

* Resolving the embedding levels from a paragraph
* Returning paragraph runs of those levels (and their directions)
* Returning the whitespace-level-reset runs for a line-slice within the
  paragraph
* Returning the reordered indices + levels for a line-slice within the
  paragraph.

#
# Bidi_Paired_Bracket and Bidi_Paired_Bracket_Type Properties
#
# This file is a normative contributory data file in the Unicode
# Character Database.
#
# Bidi_Paired_Bracket is a normative property of type Miscellaneous,
# which establishes a mapping between characters that are treated as
# bracket pairs by the Unicode Bidirectional Algorithm.
#
# Bidi_Paired_Bracket_Type is a normative property of type Enumeration,
# which classifies characters into opening and closing paired brackets
# for the purposes of the Unicode Bidirectional Algorithm.
#
# This file lists the set of code points with Bidi_Paired_Bracket_Type
# property values Open and Close. The set is derived from the character
# properties General_Category (gc), Bidi_Class (bc), Bidi_Mirrored (Bidi_M),
# and Bidi_Mirroring_Glyph (bmg), as follows: two characters, A and B,
# form a bracket pair if A has gc=Ps and B has gc=Pe, both have bc=ON and
# Bidi_M=Y, and bmg of A is B. Bidi_Paired_Bracket (bpb) maps A to B and
# vice versa, and their Bidi_Paired_Bracket_Type (bpt) property values are
# Open (o) and Close (c), respectively.
#
# The brackets with ticks U+298D LEFT SQUARE BRACKET WITH TICK IN TOP CORNER
# through U+2990 RIGHT SQUARE BRACKET WITH TICK IN TOP CORNER are paired the
# same way their glyphs form mirror pairs, according to their bmg property
# values. They are not paired on the basis of a diagonal or antidiagonal
# matching of the corner ticks inferred from code point order.
#
# For legacy reasons, the characters U+FD3E ORNATE LEFT PARENTHESIS and
# U+FD3F ORNATE RIGHT PARENTHESIS do not mirror in bidirectional display
# and therefore do not form a bracket pair.
#
# The Unicode property value stability policy guarantees that characters
# which have bpt=o or bpt=c also have bc=ON and Bidi_M=Y. As a result, an
# implementation can optimize the lookup of the Bidi_Paired_Bracket_Type
# property values Open and Close by restricting the processing to characters
# with bc=ON.
#
# The format of the file is three fields separated by a semicolon.
# Field 0: Unicode code point value, represented as a hexadecimal value
# Field 1: Bidi_Paired_Bracket property value, a code point value or <none>
# Field 2: Bidi_Paired_Bracket_Type property value, one of the following:
# o Open
# c Close
# n None
# The names of the characters in field 0 are given in comments at the end
# of each line.
#
# For information on bidirectional paired brackets, see UAX #9: Unicode
# Bidirectional Algorithm, at https://www.unicode.org/reports/tr9/
