Please see attached for a sample source document and the result pdf. We are using version 17.2.0

Hi Kunal,

Thanks for your inquiry.

Unfortunately, your issue is not resolved yet and there are no estimates available. Our product team has completed the analysis and the root cause of this issue has been identified. The Thai characters require the support of advanced typography. Unfortunately, Aspose.Words currently does not support such features. Because of complexity, the implementation of the fix of this issue has been postponed till a later date. We will inform you via this thread as soon as this issue is resolved. We apologize for any inconvenience.

Best regards,
