Fix cursor position issue with astral symbols 
In case of astral symbols like Devanagari matras multiple wide-char codepoints
occupy a single position/column. Positioning the cursor wrt. the actual number
of wide-characters in a wide-char string gets "visually incorrect".  The trick
is to calculate the correct number of columns needed to represent a fixed-size
wide-character string.

Relevant man pages:

1. wcswidth(3)
2. wctomb(3)
3. mblen(3)
