Incorrect column highlight position with non-English characters

[tomasz1986]

When using non-English characters, the highlight position gets moved further to the right. My guess is that the non-English characters are actually coded using multiple symbols.

For example, try to copy and paste the Korean word 닭 into Notepad++. This is just one syllable, but is comprised of 4 actual letters. The highlight position will move 1 space further to the right than necessary.

Now, looking at it, it seems that the ruler position is incorrect either.
