Hello,
thanks for your hint.
The missing letter transliteration is no bug. The current version supports the Bulgarian
alphabet only and this does not have the "yery".
You may use the ISO 9 Standard for Russian texts instead of DIN 1460 BUL, as ISO 9 is
universal for all cyrillic alphabets .
Nevertheless a Russian transliteration will be added in future versions soon.
Regards,
Alex Linke
