--- Comment #13 from V Stuart Foote <vstuart.fo...@utsa.edu> ---
Not clear if the (isRTL) is applied logically to do the mirror::String() [1]? I
get confused walking through the code. Where we check for RTL [2] checking
character by character with GetCharacterClassification () [3] using the ICU lib
getUnicodeDirection() by Unicode block [4] to classify the text run.
So the string should be mirrored/reversed when written out to document canvas.
But something is misapplied.
