If not, see # . # Current Lithuanian braille alphabet was officially standardized # in 2000. # # Much more complete Lithuanian 6-dot braille was standardized as a # National Annex to ISO 17049 in 2019, officially designated as # LST ISO 17049:2017/NA:2019. This document is referred to as # "the Standard" below. The Standard is available for purchase from # the Lithuanian standards body (lsd.lt). # # The relevant ISO standard is called "Accessible design ‐ Application # of braille on signage, equipment and appliances", so the Standard # focuses on printed or otherwise preproduced Braille, so, as is often # the case, it's very context dependent and has several clashing dot # mappings even if you consider literary braille (section NA.1) only. # # The authors of the Standard were aware of our prior work on this # table, but they chose to ignore us, this table, and its existing # users entirely, and standardized even the literary Braille differently # than we had it already implemented without so much as a discussion # with us. Also, the Standard makes no references to Unicode. # As a result, this table had to be revamped to become closer to the # Standard. It does not match the Standard completely though. # # Some definitions in this table are marked as noback. Typically they # are not defined in the Standard and act as convenience aliases. # They are okay to skip if implementing them is not possible. ### ### TABLE METADATA ### #-index-name: Lithuanian, 6-dot #-display-name: Lithuanian 6-dot braille #+language: lt #+type: literary #+contraction: no #+dots: 6 #+direction: both #+version: 2019 #-updated: 2025 ### ### WHITESPACE ### include spaces.uti ### ### LETTERS ### # Base Latin letters. include latinLetterDef6Dots.uti # Letters with diacritics which are part of the Lithuanian alphabet. lowercase \x0105 16 ą LATIN SMALL LETTER A WITH OGONEK lowercase \x010d 146 č LATIN SMALL LETTER C WITH CARON lowercase \x0119 156 ę LATIN SMALL LETTER E WITH OGONEK lowercase \x0117 345 ė LATIN SMALL LETTER E WITH DOT ABOVE lowercase \x012f 246 į LATIN SMALL LETTER I WITH OGONEK lowercase \x0161 2346 š LATIN SMALL LETTER S WITH CARON lowercase \x0173 346 ų LATIN SMALL LETTER U WITH OGONEK lowercase \x016b 1256 ū LATIN SMALL LETTER U WITH MACRON lowercase \x017e 126 ž LATIN SMALL LETTER Z WITH CARON base uppercase \x0104 \x0105 Ąą LATIN CAPITAL LETTER A WITH OGONEK,LATIN SMALL LETTER A WITH OGONEK base uppercase \x010c \x010d Čč LATIN CAPITAL LETTER C WITH CARON,LATIN SMALL LETTER C WITH CARON base uppercase \x0118 \x0119 Ęę LATIN CAPITAL LETTER E WITH OGONEK,LATIN SMALL LETTER E WITH OGONEK base uppercase \x0116 \x0117 Ėė LATIN CAPITAL LETTER E WITH DOT ABOVE,LATIN SMALL LETTER E WITH DOT ABOVE base uppercase \x012e \x012f Įį LATIN CAPITAL LETTER I WITH OGONEK,LATIN SMALL LETTER I WITH OGONEK base uppercase \x0160 \x0161 Šš LATIN CAPITAL LETTER S WITH CARON,LATIN SMALL LETTER S WITH CARON base uppercase \x0172 \x0173 Ųų LATIN CAPITAL LETTER U WITH OGONEK,LATIN SMALL LETTER U WITH OGONEK base uppercase \x016a \x016b Ūū LATIN CAPITAL LETTER U WITH MACRON,LATIN SMALL LETTER U WITH MACRON base uppercase \x017d \x017e Žž LATIN CAPITAL LETTER Z WITH CARON,LATIN SMALL LETTER Z WITH CARON ### ### DIGITS ### include digits6Dots.uti include litdigits6Dots.uti ### ### PUNCTUATION ### punctuation \x002c 2 , COMMA punctuation \x002e 256 .
