I recently converted lot of PDF in Google doc, It by default creates lot of markup to the document. I want to only retain bold and italics and remove all other formatting while converting to markdown. I tried this

-t markdown-header_attributes-link_attributes-native_divs-native_spans-styles

but resulting markdown still conatins markup like this **[Tomorrow  12]{dir="ltr"}** I needed only **Tomorrow  12**. How can we achieve this. Please help.
