We use and adjust the Hebrew Localization in our account.
When working on the "Welcome to Populi" email, I saw that even though some of the paragraphs were only in Hebrew, they too were aligned to the left and the direction was ltr. Not scrambled as in bidi-override, but the punctuation was to the right of the text, like here:
שלום!
seeing there were html line brakes in the original translation, I tried adding a div tag, but that was obviously blocked and backfired.
Without changing both text direction and alignment, the emails in Hebrew will seem very unprofessional, as one of the main things we do is teach Hebrew.
It can be added in the Localization view or in the place I suggested Here (if and when it happens)
