Re: sorting greek and russian text

[Peter Gulutzan]

Although utf8_general_ci has some defects and
I often prefer utf8_unicode_ci, I see no
problem with basic sort of all letters of the
Greek alphabet. For example:

mysql> create table t (s1 char(1) character set utf8 collate utf8_general_ci);
Query OK, 0 rows affected (0.12 sec)

mysql> insert into t values ('Α'),('Β'),('Γ'),('Δ'),('Ε'),('Ζ');
Query OK, 6 rows affected (0.00 sec)
Records: 6 Duplicates: 0 Warnings: 0

mysql> insert into t values ('Η'),('Θ'),('Ι'),('Κ'),('Λ'),('Μ');
Query OK, 6 rows affected (0.00 sec)
Records: 6 Duplicates: 0 Warnings: 0

mysql> insert into t values ('Ν'),('Ξ'),('Ο'),('Π'),('Ρ'),('Σ');
Query OK, 6 rows affected (0.00 sec)
Records: 6 Duplicates: 0 Warnings: 0

mysql> insert into t values ('Τ'),('Υ'),('Φ'),('Χ'),('Ψ'),('Ω');
Query OK, 6 rows affected (0.00 sec)
Records: 6 Duplicates: 0 Warnings: 0

mysql> select * from t order by s1;
+------+
| s1 |
+------+
| Α |
| Β |
| Γ |
| Δ |
| Ε |
| Ζ |
| Η |
| Θ |
| Ι |
| Κ |
| Λ |
| Μ |
| Ν |
| Ξ |
| Ο |
| Π |
| Ρ |
| Σ |
| Τ |
| Υ |
| Φ |
| Χ |
| Ψ |
| Ω |
+------+
24 rows in set (0.01 sec)

I did the above with MySQL 6.0 but I doubt that
earlier versions work differently.
