~/.minttyrc-test:

Running mintty '3.7.7' via mintty -c ~/.minttyrc-test, and then open vim and type some alphabets and Hangul characters, as shown in the image below.

Hangul characters occupies two cells in terminal and and are left-aligned.
Because of this, the right ) leaves a larger space before it compared to the left (.

Pretendard is not a monospace font, as far as I know.
I would like to align Hangul characters in the center to balance the spacing, without using a monospace font.
Is there a way to achieve this?
