Use subsurface_os_feature_available() to check for unicode stars support

Browse source 
Mainly affecting older Windows (such as XP), which do not have a more
fully featured unicode fonts installed, such as Arial Unicode MS.

With this patch we do a runtime check of the OS version in a couple of
places and if the OS is old, we use the asterix character and spaces instead
of the unicode star characters.

Linux and OSX should be unaffected by this change unless
subsurface_os_feature_available() returns FALSE for UTF8_FONT_WITH_STARS
at some point.
