Current State:

Jira mobile app supports Georgian language rendering throughout the native UI. That means if the Georgian language is used in Jira fields or comments it is render correctly. 

But any  Georgian text within Forms rendered as "###" on Jira mobile app (both Android and iOS impacted). 

Proposed Future State:

Support Georgian text when Forms are opened from Jira mobile app

Alternative (e.g. Third Party Plugin):

No known workaround or plugins available.
