vt: selection: take screen contents from uniscr if available
This preserves whatever was written even if we can't currently display the given glyph. Mouse paste won't corrupt any character of wcwidth() == 1 anymore. Note that for now uniscr doesn't get allocated until something reads /dev/vcsuN for that console, making this code dormant for most users.
