Description: varchar/text operator "=" not unicode safe?
Details:
I have a UNICODE database, trying to compare two unicode strings (Ethiopic
characters). Client encoding is also UNICODE:
testdb=> select 'á áµá© áá´á'='á°áá á¨á á°';
?column?
----------
t
(1 row)
Clearly, it can be seen that they are not equal. The "LIKE" operator also
seems to think so:
testdb=> select 'á áµá© áá´á' LIKE 'á°áá á¨á á°';
?column?
----------
f
(1 row)
What is the problem here?
The behavior is the same with SQL_ASCII databases and the SQL_ASCII client
encoding.
