[FriBidi] Mixed RTL and numeric strings

[Ian Walberg]

Behdad,

Ok good .....

What we have been requested to do is always put the minus sign on the left hand side of the number (12345) digits even when the left is RTL.

We are experimenting with combinations of characters this afternoon but are not sure what might work or if this is even possible. Currently we always see the minus sign on the right hand side when the test is RTL.

Many thanks

Ian

Snap.  That's exactly why U+066x digits and U+06Fx digits have different types.  So, MINUS SIGN is supposed to work both for Arabic and Persian digits.
