|
||
# 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 has been in effect since 2011-04-13 (its assigned
|
||
# 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 defines two 1:1 mappings between ISO-8859-13 8-bit
|
||
# character set and 8-dot Braille writing system, called "literary" and
|
||
# "computer" braille codes. Due to the nature of the Standard, both
|
||
# mappings contain lots of useless definitions (e.g. for control
|
||
# characters), while some other sensible definitions (like one for
|
||
# the € sign) are simply missing due to the relevant characters not
|
||
# being part of ISO 8859-13. Additionally, it seems like very little
|
||
# effort (if any) was made to align these 8-dot tables with the 6-dot
|
||
# braille that was already in use by Lithuanian braille users.
|
||
# Furthermore, the definition of not one but two mappings like this
|
||
# seems questionable at least, and the Standard even contains a few
|
||
# errors, such as incorrectly named characters and conflicting mappings.
|
||
# In practice, the Standard seems barely used, if at all.
|
||
#
|
||
# lt.ctb is based on the literary table described in the
|
||
# Standard. This table (lt-8dot.utb) was the result of revamping the
|
||
# original 8-dot table (lt.ctb) in 2025 and aligning it closely with
|
||
# our 6-dot braille table (lt-6dot.utb), which is actually used by the
|
||
# people.
|
||
#
|
||
# Some definitions in this table are marked as noback. Typically, they
|
||
# act as convenience aliases. It's okay to skip implementing them if
|
||
# doing it is not possible or too difficult.
