The bug is the inconsistency. I have opinions, for what they're
worth, on how it should behave:
- Reverting to the old value is better than clobbering to zero;
if it can't change the field to what I asked for (because
what I asked for was bogus) it shouldn't change it at all
- Leaving the bogus input in Debit, and only cleaning it up on
exit from Credit, is kind of ugly and could be confusing
But far outweighing those is that all variations should behave
the *same* way.
None of the current behaviours give incorrect results in the end;
it's just a usability thing -- which is why I called my complaint

What I personally would prefer instead of a dialog that one has
to dismiss is a simple beep, like vi used to do on error, when
you were using an actual serial terminal. But I pretty much
expect to be outvoted on that...

That would be a libc failure rather than a GnuCash one, but I don’t have a lot of confidence in libc’s localization mechanisms.
You're right; I can see that being a problem. If it's libc's
fault, though, it's likely to be platform-dependent, isn't it?
That adds another dimension to the difficulty of trying to fix it
in application code.

Semi-resigned. I have some souvenir Nepali and UAE currency left
over from a trip, and each country's bills contain both their own
and Western[*] numbers, and their own and English text. I
suspect you're right, though, that people are rather more
resigned to doing things our way when computers are involved.
[*] We call our numerals "Arabic", but most(?) of the Arab world
actually uses different ones -- somewhat related to ours, but not
closely enough to be very legible to my Anglo eyes. I believe
ours are descended from a regional variant that was, and is, used
only in parts of North Africa -- and thus in Moorish Spain, from
where the rest of Europe got them.
