# BRLTTY Text Table - Lituanian
#
# Copyright (C) 2017 Rimas Kudelis <rq@akl.lt>
#
# The Lithuanian 8-dot Braille writing system is described in a decree of the Minister of
# Social Security and Labor, called "Dėl vieningos aštuonių taškų Brailio rašto sistemos
# naudojimo tvarkos aprašo patvirtinimo", which is in effect since 2011-04-13. Document
# number is A1-183. At the time of writing this file, the document was accessible at
# https://www.e-tar.lt/portal/lt/legalAct/TAR.443D667CA047 .
# The document is referred to as "the standard" below.
#
# The standard maps ISO-8859-13 character set to 8-dot Braille writing system. However,
# even though it defines different mappings for literary and computer braille modes, it
# doesn't seem like the authors had a good understanding of why these two modes exist
# and how they differ. Furthermore, the standard contains a few errors (incorrectly named
# characters as well as mapping conflicts). I would say it needs further improvements.
#
# This file is based on the standard, but does not exactly follow it. Some standard
# definitions are commented out, some changed, and some extra ones are added.
#
# This table is based on the respective liblouis table.
