Dear Karel,
The server encoding and the client encoding are
LATIN1. These results are from phpPgAdmin:
This is ok:
select ascii('ª')
ascii
-----
170
select chr(170)
chr
---
ª
select to_ascii(chr(170))
to_ascii
--------
a
But this is not ok!
select ascii('º')
ascii
-----
186
select chr(186)
chr
---
º
select to_ascii(chr(186))
to_ascii
--------
select ascii(to_ascii(chr(186)))
ascii
-----
32
I think that if to_ascii of ª (170) is a, then
to_ascii of º (186) should be o, and not space.
