The differences won't matter for for this questioner.
In case anyone sees this and thinks "general" is just as good,
I add a warning that "unicode" is better for obscurer cases.

For example, here are two MySQL-collation-sequence charts:
http://www.collation-charts.org/mysql60/mysql604.utf8_unicode_ci.european.html
http://www.collation-charts.org/mysql60/mysql604.utf8_general_ci.european.html
Scroll down till you see the Greek characters alpha beta gamma
delta epsilon. Notice the next characters after epsilon.
In the "general" collation the next character is zeta.
In the "unicode" collation the next character is digamma.
One never sees digammas in the Bible,
but the "unicode" collation is correct
