Fix v2 for #10426

Note: In v1 we fix this by transforming into unicode just before we use
it (when we send it to jinja2) because jinja2 cannot handle non-ascii
characters in str.

In v2 our model is that all text values need to be stored as unicode
type internally.  So we transform this to unicode when we read it from
the inventory file and save it into the internal dict instead.
