In poking at this, I've discovered some inconsistency in the
register's handling of (what I believe to be) invalid input.
This isn't new; it's the same in GNC 3.0 and 2.6.18.
In a text field (I've tested a txn's description and a split's
memo), both U+e9 ("é", e-acute) and U+1f600 ("😀", grinning-face
emoji) are accepted, displayed, and stored correctly as UTF-8 by
the XML back end. OK so far.
But in a currency-amount field (I've tested specifically a
split's Debit field, and all of the following cases are described
in those terms):
I type Result
abcd<ENTER> Each of these behaves like "0<WHICHEVER>":
abcd<TAB> - Debit becomes blank (ie. zero)
- Focus moves as appropriate for
a5 as above
5a<ENTER> Nothing happens. The Debit field
containing "5a" remains focused, even
after repeated <ENTER>s
5a<TAB> 1. I get an error dialog: "An error
occurred while processing 5a."
2. When I dismiss the dialog, GNC focuses
the Credit field, leaving the
"5a" in the Debit field (the former
is somewhat surprising; the latter
very much so!)
3. When I then <TAB> or <ENTER> out of
the Credit field, Debit returns to its
- N.B.: This is unlike "abcd<TAB>",
which sets Debit to zero
An e-acute it treated like "5a" above (even if I don't type any
abécd<ENTER> As for "5a<ENTER>" (except that the cursor
jumps to just before the offending "é")
abécd<TAB> As for "5a<TAB>"
If I repeat the previous two cases with the grinning-face emoji
(U+1f600) in place of the e-acute, the emoji is ignored
completely -- it doesn't display, and exiting the field behaves
as if I'd typed "abcd", i.e. as if I'd typed nothing at all, i.e.
it gets forced to zero.
All of those are invalid inputs for Debit, I presume. So it's
not a problem that they're all rejected -- only that they're
- Ubuntu 16.04
- GNC 3.0 and GNC 2.6.18 (same results with both)
- XFCE (not sure if that matters)
- Locale-related bits of GNC's environment:
- Autosplit Ledger mode in effect for the account in question
Nitpicky details, to be sure. Is any of it worth filing a bug
