[Version] N/A
[Project] N/A
[Title] Fix the smallcaps-italic combination issue
[BinType] N/A
[Customer] N/A
[Issue#] N/A
[Solution] The combination of small-caps and italic is synthesized. If there is a combination of smallcaps and italic then the fon
          cache will give the normal font and we will synthesize(skew) that font face.
