This was fixed for passwords in the database by having a dotted zero.
Would be nice to use it for database password entry, as well as other fields (user name, comments, custom ...), so that someone wondering what zeros look like might get a hint from an "obviously numeric" field - including the Modified & Accessed.
Is there a reason not to use this font consistently?
Even more helpful might be to display the "Il10O" (Capital-I, Lowercase-l, One, Zero, Capital-O) sequence on-screen.
