Dear Bram,
I believe this patch contradicts the spirit of Vim digraphs since Vim 6,
which is expressed in digraph.txt as follows:
*These are the RFC1345 digraphs for the one-byte characters. See
the output of*
*":digraphs" for the others. The characters above 255 are only
available when*
*Vim was compiled with the |+multi_byte| feature.*
*EURO*
*Exception: RFC1345 doesn't specify the euro sign. In Vim the
digraph =e was*
*added for this. Note the difference between latin1, where the
digraph Cu is*
*used for the currency sign, and latin9 (iso-8859-15), where the
digraph =e is*
*used for the euro sign, while both of them are the character 164,
0xa4. For*
*compatibility with zsh Eu can also be used for the euro sign.*
RFC 1345 has a very special logic behind its digraphs (e.g., the grave
accent is marked by an exclamation mark, so that è is entered as
<C-K>e!, rather than <C-K>e`, ê is entered as <C-K>e> rather then
<C-K>e^, etc), which is very consistent, logical, and mostly - a standard.
I also believe that digraphs that are not defined should prompt an
error, unlike the situation today, when you hit bad combination, the
first character is ignored: For example, if you hit <C-K>ff you get, as
you should, the digraph for the ff ligature, but if you misstype
<C-K>gg, instead of getting an error indication (like zsh does) you
simply get a g.
Finally, I believe that if one is interested in resurrecting Vim 5
digraphs, the solution should be to knowingly source some runtime file
which defines these extra digraphs.
Best,
Zvi.
