Well, you can learn actual basic braille in like 15 minutes. The only important thing missing in it is ⠼ that denotes that following symbol is a a number. E.g. ⠁⠃⠉ is “abc” but ⠼⠁⠃⠉ is 123.

A neat trick is that it translates mostly phonetically across languages so, when traveling, you can get some idea and even practice a bit of reading of the local script by reading braille signs in elevators and buses. It is surprisingly difficult to find photos of those signs on the internet, even though they are literally everywhere, but, for example, this sign reads as KNOPKA V?ZOVA PERSONALA in braille, so you can infer that “КНОПКА” reads as “knopka” and not “khonka”, or that З thing is not a number but actually a letter for Z. The only uncommon letter here is Ы, but it is notoriously difficult one, and you can skip it in most words and people will still understand you. It might be even more helpful with wildly different script like hebrew, but I haven’t tried that myself yet.
