Editing a PDF that uses Inter
Most PDFs embed only the letters they already use. Type a new letter and many editors either refuse or swap in a different font. MythosPDF recognises Inter from the widths stored in your PDF, loads the complete open font, and sets your new text in Inter itself. The rest of the page is carried over untouched.
