Usage of RLM and LRM buttons for Hebrew

Hi all,

we have some problems to understand how RLM and LRM buttons need to be used in case of

  1. alphanumeric sequences
  2. numbers
  3. product names that remain in English
  4. commas
  5. brackets

can I find anywhere a kind of style guide so that we know where the "arrow" characters need to placed in order to have a correct visualisation of the text in the translated file?

Thanks so much for any kind of help,

Francesca
