i18n: use encoding.colwidth() for correct column width

Some encoding and language combinations (e.g.: UTF-8 and Japanese)
cause encoding characters into sequence of bytes more than column
width of them.

So, encoding.colwidth() should be applied instread of len() on i18n
strings.

In addition to it, formatting by '%*s'/'%-*s' also uses "number of
bytes" to calculate space padding size, and should be fixed, too.
