On the matter of backward text, I did a little research and found this:
At the point where
@IshChayil began typing Hebrew in his mixed-language
post earlier in this thread, an invisible character was inserted that tells computers to render the characters from right to left, thus overriding the left-to-right direction of English. This invisible character is called, fittingly enough, a "
right-to-left-override" (or RLO for short).
The following line of numbers, typed in ascending order from 1 to 6, has an RLO between the 3 and 4:
123456
If you see "123654" then your computer has support for
bi-directional text.
Editing text that has an RLO hiding in it can be tricky but that doesn't mean your system has a problem.
Some systems do render things incorrectly, however. For instance a reversal in one line is not supposed to extend into subsequent lines. If the following line is backwards then the app or operating system you're using may lack full Unicode-BiDi compliance:
Testing 1-2-3
Ish, to prevent "Jewish caps lock" from affecting subsequent non-Hebrew text, you can insert a "pop-directional-formatting" character (U+202C) at the end of each Hebrew section, though I'm not sure how one would enter it on your system.
One site says to type "Alt +202C" on Windows. On macOS I found it in the Characters palette.
