OS: macOS Sierra 10.12.6
Resolume version: Arena 6.0.3 rev 60620
'Text Block' generator source does not properly display commonly used characters with default font 'Arial Black'.
Steps to reproduce:
1) Start a new composition.
2) In the Sources browser panel, pick 'Text Block' from Generators.
3) For the 'Text' setting of Text Block replace the text "Resolume" with "1 2 3 4 5 6 7 8 9 0".
4) Confirm the result in Output Monitor or Preview Monitor.
I only mention numerals in the 'Steps to reproduce' but there are more characters affected, like the 'M'.
