[fpc-pascal] Fwd: Re: fcl-report demos not working on windows10/64 with win64 compiled - Font Arial not found

[Andreas Frieß]

Hello Michael,

if the font is not found, why is there not the correct indication of the
missing font ? The errormessage is in this case completly wrong.

If a fallback should be possible, it should work and not mask the
problem and create a false errormessage.

Maybe the font liberation Sans is not on a Windows10/64 machine, if this
is true i should see the message -> fpreport: Could not find the font
<Liberation Sans> in the font cache.
Or
-> EReportFontNotFound: >> Font not found: "Liberation Sans".
