Software handles the network; hardware handles the power. MISAll keeps selling offline when the link drops, but a computer that loses power mid-transaction is a different risk — that one is solved with a UPS on the till and the router.
People often ask these as one question and they are not. An outage on the line is a software problem and it is handled: the terminal switches to offline mode and syncs later. An outage on the mains is a hardware problem and no software setting helps.
The cheap version of the fix is a small UPS that carries the till computer, the router and the receipt printer for fifteen to thirty minutes. That is enough to finish the transaction in front of you and shut down cleanly, which is the actual goal — not trading through a four-hour cut.
If cuts are daily where you are, budget for it as equipment rather than treating each one as an incident. Shops in Lusaka, Kampala and Cotonou generally end up with a UPS per counter and a plan for who shuts what down.
This sits in the POS. Licensing is covered on pricing, and the rest of the questions are in Answers.

Yes. In MISAll the interface language is a property of the user account, not of the installation, so the back-office machine can run in Chinese while the front counter runs in English, Spanish, Arabic, Khmer or Indonesian at the same time.
Because the printer is being asked to render characters that are not in its built-in font table. The fix is to stop sending text and send the receipt as a rendered image instead — MISAll can print in graphic mode, which is why non-Latin scripts come out readable.
MISAll switches to offline mode automatically and keeps taking sales; the transactions sync once the connection returns. You do not have to notice the outage or press anything.
