This commit adds fixes to Russian Braille. Now the test with parentheses is passed. Also there are devision and multiplication signs have been modified according to the Russian braille specs.
This commit adds a layer of Latin and Greek alphabets for Russian mathematical Braille. * In unicode.yaml Latin and Greek letters now go through the internal markers of the alphabetic mode. • In braille.rs russian_cleanup turns these markers into real signs: ◦ Latin lowercase: ⠠ ◦ Latin uppercase: ⠨ ◦ Greek lowercase: ⠰ ◦ Greek uppercase: ⠸ Added tests to russian.rs to x+A+y+B, the Latin letter after the number.
This commit adds Roots, powers and scripts according to the Russian math Braille specs.
Fix YAML replace syntax and extend Russian braille rules: add chemical-formula-operator-bond and prefix-geometry-ops rules, broaden function-name matching (include tg/ctg variants) and add separator markers. Update unicode mappings (degree sign, invisible characters, conditional ∪ mapping, parallel/arrow glyphs) and adjust several function/operator braille outputs. Add/expand tests to cover functions, geometry, matrices and chemical formulas to validate the changes.
