Well the more resources, the better. (Not sure if the grammar is correct here). In my link I found other similarities too not only the well known RU/BG Cyrillic. There are letters like S J Y etc. I didn't knew were Cyrillic from Ukrainian, Belarusian, Serbian etc. Hope I can make a list as soon as I get to a pc.
That's true. But, yours had what mine had in it, and more. So wasn't any point really. I was also unaware of the different languages usage of Cyrillic.
