Hi, I am using the new TextRenderInfo.GetCharacterRenderInfos method within my
own ITextExtractionStrategy.
But it always gives an exception:
Unhandled Exception: System.ArgumentOutOfRangeException: Index and length must
refer to a location within the string.
Parameter name: length

Boolean fAlwaysCopy)

Int32 charIndex, Single horizontalOffset)
