Identify text font Unicode or Non-unicode?

Dear Support,
I wanted to identify the text is a non Unicode font or Unicode font without using the Font name. Consider that I don’t know which font I have used, but now I wanted to check and change the Unicode font to non-Unicode font. Is this possible in Aspose.Words?

Hi John,
Thanks for your request. I am not sure what you mean. Could you please attach sample document for testing? I will investigate the issue and provide you more information.
Maybe you can try using LocaleId:
Best regards.
