issue-#185 font names must be quoted in XhtmlExporter

[Robert]

I could find no existing discussion of this topic https://redmine.blackboxframework.org/issues/185.
Is it dormant?

[Josef Templ]

The standard seems to request this but all the browsers I have tested
also support unquoted font-family properties even if they contain spaces.
It seems to be very common to not use quotes here.
It is also not easy to find out what the standard really defines.
In my W3C subsystem on CPC unquoted font-family properties are also supported.
So I think we can ignore this and remove the issue.

I also think this issue could be removed, unless someone reports an actual problem. I could make its status "Rejected".

There is also a "stale" branch in Github, I don't know how that should be handled.

[Josef Templ]

I have removed the stale branch and set the issue to rejected.

Note that this issue has been rejected without a vote, and could be reopened later if necessary.
