These values are in all Adobe fonts, and I think they are in many other
fonts from other vendors, too.

Be careful, when you are mixing fonts on one line of text, to compare
underline positions and thicknesses of adjacent fonts.  You may want to
pick just one value for the whole line (indeed, perhaps the whole
page), to avoid unsightly variations in underlines when there are font
changes.  It is purely aesthetics, and you may choose to disagree with
my feelings, but at least think about it or print some tests and look
at them.
