#
# Two computer braille systems are in use in Portugal and Brazil: the
# 6-dot variant and the 8-dot variant. This table implements the 6-dot
# variant. The 8-dot system is implemented in pt-pt-comp8.ctb. 8-dot
# computer braille may be derived from 6-dot computer braille through
# a conversion system.
#
# This file is derived from the project called BrailleCor was first
# presented on May 28, 2024, at the International Council on English
# Braille Assembly held in Auckland, developed by Iván Argote-Pérez.
#
# This table is mainly based on the official Portuguese 6-dot computer
# braille code; defines accented letters, punctuation marks, currency
# signs, Greek letters, some math symbols and other characters/rules.
#
# For the omissions in the official documentation, they were solved
# using approximate character definitions of this table itself and
# resources from other tables so that such gaps would not be left
# uncovered.
