That is the expected, by the spec, behavior of the slash characters with numbers. It might be unfortunate, but that what the Unicode Bidirectional Text algorithm mandates. MS Office is known to not follow the spec here.

The good thing about specs is that everyone follows them, otherwise copying text from another application (e.g. your web browser or text editor) is suddenly rendered differently.

It is not that hard to type the date in the order you want, BTW: ١٢/٣/١٩٧٨ is no easier than ١٩٧٨/٣/١٢.

What about when you just have a slash after a few digits with no other digits afterwards? i.e. the line is set to RTL, and let's say I even entered some strongly-RTL characters; then a space; then some digits; and now I type a slash. What does the UBA say about where that slash is supposed to appear?
