Description

The Typography.NumeralStyle="OldStyle" property is not respected by WPF 4 when the text being displayed consists solely of numbers and punctuation. It appears that Old Style numerals are only used when the run being formatted/displayed also contains letters.

While this is easiest to demonstrate with <TextBlock>, code that uses TextFormatter directly is also affected.

I am also experiencing this. This is a massive showstopper for us as our application is reports-centric and OpenType support was one of the reasons for us adopting WPF. We are experiencing the following:

- WPF seems to default to OldStyle, proportional numerals.
- We cannot change either Typography.NumeralStyle or Typography.NumeralAlignment on runs containing only numbers.
- As a result, our reports look horrible.

Is there a way for me to at least change the defaults so that we will have lining, tabular figures everywhere? The fact that Bradley's problem is changing _to_ OldStyle numerals would suggest this. As most runs that should have proportional figures also contain text this would be an acceptable workaround for us until a hotfix is available.

Hi Bradley,

We've been able to determine that this issue is caused by a defect in a binary that ships as part of Windows. Unfortunately, there's no workaround. We're currently following up with the Windows team to see if they can produce a hotfix for this issue or fix it in their next release.

Thanks,
WPF Team

I ran into the same problem using Typography.Variants of Subscript and Superscript and reported it a few days ago. Microsoft was able to reproduce the bug and is working on it. Looks like it affects all Typography attached properties. (E.g. Typography.Capitals of AllSmallCaps fails too.)
