We are required to include Khmer and English text in our invoices. In the past we could do this by importing a .docx invoice template but this is no longer possible (according to https://quickbooks.intuit.com/learn-support/en-us/reports-and-accounting/re-importing-custom-invoice...).
We've tried using the builtin invoice templates (following https://quickbooks.intuit.com/learn-support/en-us/customize-forms/customize-invoices-estimates-and-s...) and we can type in Khmer text and it looks fine in the editor but when we generate invoices or click "Preview" all the Khmer text is missing (or question marks) - see screenshot below.
Is it possible to use non-English characters in invoices? Surely we aren't the only ones in the world with this requirement?
We're on Quickbooks Online Advanced if it makes a difference.
