+    Use exactly this formula also for calculating the width array values. The units patch below is 
+    meant for opentype cff fonts that don't use the recommended 1000 units per em and was tested 
+    for a few fonts by HH and MS (2023-11-01). We explicitly check for the deviation from 1000 
+    in order to be compatible and only touch the few fonts that are sensitive for this. The patch 
+    makes sure that copying works (in spite of the accessibility hype viewers still have to gamble 
+    on what a space is; so much for standards) and also has the side effect of a bit more compact 
+    character streams. It's one of these cases where one wonders if it was really worth spending 
+    that much time on (because after all, it worked ok in luametatex).
