In latest version this fix:
show proper currency symbol in taxes and charges table [#26827] & [#26935] is not working in PDF standard format for Quotation Document. It shows fine in the print preview of the Quotation, but when converted to PDF it shows the Tax currency is the account or company currency not the document currency. It needs a second look to from print format point of view.
Posting a Github issue would be great. I also noticed this issue on several other doctypes (e.g. the Assets don’t support different currencies and the dashboard shows $). I guess this is a legacy bug from the time when ERPnext didn’t have multi-currency support?!
