Are you sure the font supports all of those characters?  What font is
used for them in each case.

And again, you don't show the text that doesn't render correctly (as
characters), so it's impossible to investigate the cases you tried.
Images help to see how stuff is displayed, but they cannot be used to
reliably figure out what text was displayed.  I asked you to show the
actual text many times.
