Formatter that convert double-minus into emdash, single-minus into dash, make some minor corrections with nb-spaces and short words, wraps (c), ®, ™, § & some other pretty symbols.
Formatting rules are based on typographical standards for russian books, our own heuristics & oriented on, again, russian users primarily. However, if you like the way text is formatted here, you could use it on your own.
Formatting rules & formatter base were developed by 
Pixel-Apes group.
