Mac times count only the translation, with the language already downloaded. In these runs the table, headers and footers, two columns, lists and colors stayed in place, and Cyrillic and Spanish accented letters came out correctly. The runs also showed typical machine translation slips on short labels, such as Details of the parties becoming Detalles de las fiestas. More on what to check is in translate a PDF and keep the layout.

Right to left and complex scripts
In As original mode the translation is drawn over the page in the original frames. For Latin, Cyrillic and Greek the app uses open fonts close to common document fonts; other scripts are drawn with a system font. For Arabic the app sets right to left layout, but we have not yet checked a translated Arabic page by eye. The same goes for Hindi, Thai, Chinese, Japanese and Korean: the languages are in the list, and we will mark results here only after a run.
How language downloads work
Languages are downloaded by iOS, not by Twinpage, the first time you need them. The download needs a connection; after it, translation works offline. We have not measured download size or time on a phone yet. Tips for preparing before a trip are in offline document translation.
