fix(transliterate): handle Cyrillic back and forth

[noomorph]

Fixes reverse transliteration from the non-Latin-etymological alphabet, e.g. Cyrillic → Latin:

На возвышености овца, ктора не имѣла вълнѫ, увидѣла коњев. Прьвы тѧгал тѧжкы воз, вторы носил велико брємѧ, третји брзо возил мѫжа.
 Овца рѣкла коням: «Боли мнє срьдце, къгда виџу, како чловѣк владаје коньами.»
 Конји рѣкли: «Слушай, овцо, нам боли срьдце, къгда видимо ово: мѫж, господарь, бере твоѭ вълнѫ, да бы имѣл дља себе тепло пальто. А овца ѥсть без вълны.»
 Услышавши то, овца избѣгла в рӑвнинѹ. | Одјезд.
