Hi Sam,
And thank you very much for your reply and explanation. Much appreciated.
I will dig a bit deeper and try to figure out what is happening here.
My C is a bit rusty though, but good time to refresh it.

Any suggestions on an area to look more into?

Cheers
Bengt

<br>
This test checks what happens when text cannot be converted to a different=
=C2=A0 <br>
character set. The expected result is that the non-convertible text gets=C2=
=A0 <br>
skipped. Your output shows that, instead, non-convertible characters get=C2=
=A0 <br>
replaced by asterisk characters.<br>
<br>
That&#39;s all that can be determined, based on the above. courier-unicode =
does=C2=A0 <br>
need to know when text cannot be properly converted from one encoding to=C2=
=A0 <br>
another. Pretending that everything is cool, and just replacing the non- <b=
r>
convertible characters with placeholder characters, is not cool.<br>
<br>
Some further investigation would be needed to understand the difference in=
=C2=A0 <br>
behavior, and figure out the solution.<br>
