Let's say I want to define ,, (two commas) as a digraph for … (U+2026
HORIZONTAL ELLIPSIS). At the moment, in [g]vim 7.4.854 (with +multi_byte and
'encoding' set to utf-8),
:dig ,, 8230
does it, but
:dig ,, 0x2026
doesn't (AFAICT, it fails silently). The only way to use the hex value
explicitly is at the moment
:exec 'dig ,,' 0x2026
which is ugly.
Now the Unicode Consortium lists all codepoints by hex value, so the decimal
equivalent is losing currency. Even in HTML, where once upon a time … or
… would have been the only valid entities for that character, … is
now a third valid alternative. So why not in Vim digraphs?
N.B. Of course, if (let's say) patch 875 fixes it, "cautious" scripts will at
first either still use the backward-compatible decimal number (or the :execute
workaround), or test
:if version > 704 || (version == 704 && has('patch875'))
but it will be usable manually as soon as compiled-in.
Best regards,
Tony.
