Problem description

It's fine for single selects to have choices with values that contain spaces. Currently those can't be selected.

It's more problematic for multiple selects to have choices with values that contain spaces because multiple select values are space-separated. However, no ODK tool that I know of rejects this.

Steps to reproduce the problem

Expected behavior

Choices with spaces in them can be selected.
