Translating failed payment, payment tags and PDF invoices

How do I translate this:
"If your payment is getting failed, you can choose other payment gateways to process the payment"
"Unable to process the purchase transaction."

Also I would like to translate the "PAID" and "PENDING" tags etc. See here:

Finally how do I translate the PDF invoices?
Despite translating the invoice emails the PDFs are still english.

Hey,

Neither the tags nor the PDF invoices can be edited in other languages.
Also, the notification "Unable to process the purchase transaction." is sent from the gateway's end so we cannot give the option to edit that.

However, we are considering adding an option to edit this - "If your payment is getting failed, you can choose other payment gateways to process the payment"

We will keep you posted with the updates and will let you know once implemented.
