Fake Icon on TButton

Hi!

If you need an Icon on a button it is getting busy: TBitBtn or
TSpeedButton or even something homegrown.

On the other hand I am bothered about the increasing "kindergarden
stuff" in Unicode. But you can apply them in a useful way.

As Lazarus works with UTF8 and the OS all working with Unicode the
question arises:

What is an OS doing with a component which only allows a black font
and UTF8 chars?
Look: colored icons.

So we come to the trick to replace the ugly system icons of the
TBitBtn, colorize them and use a simple TButton.

We search the needed UTF8 Icons in the endlesse tables from the
codeblock Dingbats.

Then we insert as caption of the TButton just:

'❌ Nein'

The colored cross appears on the button - a least with gtk2.

Example in attachment.
Hope it saves work.

In Windows 10 unfortunately there is no color when I paste your
example. I also tried '✅', and it's black.
