It returns the number of ansi/widechars. In case of ansichars, that 
equals the number of bytes.

That depends on whether the character is composed or decomposed (this 
depends on your text editor and its settings, not on the compiler). If 
it's decomposed, then you get (an) extra character(s) for the decomposed 
"ยด" following the "o" (2 bytes in utf-8, 1 widechar in utf-16).
