I do not know, but with other fonts: Arial, Verdana, Consolas it works 
as expected. Do you think, that Courier New is only exception?

When I look at 
https://docs.microsoft.com/en-us/typography/font-list/courier-new I do 
not see there something special compared to other fonts ...

But my knowledge about font structures (and also about PDF internals) is 
minimal ...

I do not know if it is necesssary.

I have used FPDF port of PHP PDF library, which I have rewritten to 
pascal and there I can use "Courier New" font.
(in both ways as embedded and also when not embedded)

Probably FPDF handles PDF generation bit differently, but when I write 
into file any text in code page CP1250 and I embedd Courier New font 
(generated in advance by using makefont.php utility) then I get correct 
result.

So my raw guess was that it must be doable also using fcl-pdf somehow?
