Please check the following analysis details:
In your document the runs containing Latin letters are marked as RTL. As per description of the RTL element in ISO IEC 29500 “…This property shall not be used with strongly left-to-right text. Any behavior under that condition is unspecified…”.
MS Word however, seems to disregard RTL element for strong LTR text. We are checking if we still need to copy this behavior in Aspose.Words.
I am afraid there is no further news about this issue (WORDSNET-16497). The implementation of the fix of this issue has still been postponed till a later date (no ETA is available at the moment). We will inform you via this thread as soon as this issue is resolved. We apologize for your inconvenience.
