Similar vertical metrics-values – different behavior in InDesign

[fontelster]

I have two Fonts with nearly identical values for vertical metrics, but they behave differently in InDesign when using different first-baseline-offset. One is a regular Text-Font, one a Dingbat-Font. I found this Information in the forum

As far as I understand it, InD measures a key glyph. And that needs to be present. So I would just add Latin A-Z.

and changed some small letters to capital Letters, so I have all caps from A to Z, but the problem still exists.
These are the vertical metrics:

Textfont:

Dingbat-Font:

and these the results in InDesign:

The offset for caps-height and x-height doesn’t seem to reflect any of the vertical metrics-values. Caps-height-offset is about 770 and x-height-offset about 735.

Thanks. They don’t say wich letter is taken for measuring the caps-height, it seems to be capital E.
