Hello!
I have lc_collate and lc_ctype ru_RU.UTF-8.
And have two similar value column in different rows.
Different is that in one string have whitespace symbol, but another non
breakable whitespace symbol.
For example:
Something(whitespace)wrong
Something(non breakable space)wrong
And then when I try to create unique index I catch the error - can not
insert duplicate key in row object.
That means that the two rows are the same.
Are there any settings in postgresql that can differentiate this two
symbols?
