I am trying to decide how many spaces a Unicode character or a plain ASCII character takes in a powerpoint slide. I found that Unicode characters take more spaces than ASCII characters in general. However, to complicate the situation further, it seems that same character in different font may also take different spaces.
For example, for font arial, Unicode 我 takes four spaces, but in font 新宋体, the same Unicode character only takes two spaces.
I am wondering is there any way to decide this systematically?
