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

[Michael Van Canneyt]

As I said:

The demos do not use Arial on purpose. Probably it is used as a fallback somewhere.

So the question is: why is the demo falling back to Arial ?

It means the actually used font (Liberation Sans, line 74 of rptjson) is not found.
