Count a multibyte char width as 2 chars width

[adorechic]

Current code uses the number of characters as a text width, so that a table rows which includes multibyte characters have different width. If we put 3 byte characters to be 2 times wider than ascii characters, a table rows have same width on monospaced font.

oops, does this gem supports ruby 1.8 and 1.9? I will fix it.

I fixed to pass ruby 1.8 or 1.9 specs. PTAL!

Thanks @adorechic. I'll take a look at this hopefully this week.
