Back translating into braille with 8 dots instead of 6-dot constraint #3

Closed callumfrance closed 4 years ago

callumfrance commented 4 years ago

Some back translation taking place was creating 8-dot Braille cells. This issue was first identified on the Raspberry Pi with ViewBraille however was also replicated on Linux PC using ViewCLI.

ViewCLI: ViewCLI example of a back translation with 8 dot cells

ViewBraille: Original sample on the Raspberry Pi of a 8-dot cell being generated via translation

For reference for the ViewBraille example, the decimal value is printed however this is the unicode character that was generated https://unicodelookup.com/#10346/1

This was fixed by changing the LibLouis translation table from en-GB-g2.ctb to en-ueb-g2.ctb. The brailler now translated using Unified English Braille, Grade 2.
