Adaptive card not supporting markdown in mobile teams

[kumarUtsav-01]

Steps to reproduce

We are experiencing a problem with consistency of content displayed in an adaptive card generated when a link is unfurled.

We have a use case of showing a hyphen '-' when there is no data available for the field when the card is unfurling. As hyphen is evaluated to a dot when rendering a card, we are using − markdown for showing hyphen.

Hyphen is displayed in run time when card is rendered in browser and desktop scenario, but, the same card shows − when rendered inside mobile teams app.

Behavior in browser and desktop teams app -

Behavior in mobile teams app -

Expected behavior

Instead of showing − as text, it should have evaluated the same to a hyphen (-) when card is generated.

Actual behavior

− is shown as a string.
