Cannot select space category including non-ascii character.

Space category cannot be selected from dashboard when category label contains a non-ascii character.
For examples:

Space Category Label	Result
sample	OK
サンプル	NG

Steps to Reproduce

1. Add Space categories 'test', 'test2' and 'サンプル'
2. View the Space Categories tab. Change between categories.
   • Observe that test and test2 categories work, but that サンプル simply flicks back to the previously selected category
