Add space after prefix (invoice)

[Magnusvb]

Hello

When generate the PDF invoice from the backoffice (order page), in the header there is an invoice number like "#IN000002".

Is it possible to add a space after the #IN part (and before the number)? So it looks like this: "#IN 000002". I have tested adding a space in the settings for prefixes, but it seems to be removed when saving.

You can modify the invoice number by modifying the PS core code.
Please find the function and file path which is responsible for the generating the invoice number or title.
