By "height" do you mean "ascent" or total height?  Compare a "G" and a 
"B" in Zapfino, for example, or either of those with some of the "Z" 
variants in that font.

This has nothing to do with the height of capital letters.  Again, see 
Zapfino and compare any of the capital letters to "f" or "h".

I think you're wrong.

"not changing the line's height".
