Example SQL:
select
length(printf ('%4s', 'abc')),
length(printf ('%4s', 'äöü')),
length(printf ('%-4s', 'abc')),
length(printf ('%-4s', 'äöü'))
Output is 4, 3, 4, 3. Padding seems to take into account UTF-8 bytes
instead of UTF-8 code points.
Should padding not work on code points and output 4 in all cases as
requested?
If you are interested in a patch extending a functionality of
``printf()'' then http://sqlite.chncc.eu/utf8printf/. Adding ``l''
length modifier makes width/precision specifications being treated as
numbers of UTF-8 chars -- not bytes. ``SELECT length(printf ('%4ls',
'äöü'));'' will give 4.
