To make a long story short, few years ago I was complaining that the sort order of varchar, in UTF-8, was ignoring
blanks,that is that the sort order was:
XXXXa
XXXX a
XXXXA
XXXX A
XXXXà
XXXXb
XXXXB
But, i was in need of a sort order that would place blanks BEFORE the other char, that is I would like to have the
followingsort order:
XXXX a
XXXX A
XXXXa
XXXXA
XXXXà
XXXXb
XXXXB
Now, using Debian Jessie, I found the solution to this issue. I needed to change the file
/usr/share/i18n/locales/iso14651_t1_common
placing in the proper position the sort order.
This is the output of the diff between the file before and after the modification:
diff iso14651_t1_common.orig iso14651_t1_common
4837d4836
< <U0020> IGNORE;IGNORE;IGNORE;<U0020> # 32 <SP>
5080a5080
> <U0020> <BAS>;<MIN>;IGNORE # 32<SP>
Beware: the change is sistem wide, and regards all character sets and locales...
