# pylint: disable-msg=W0105
"""InnoDB doesn't support unique constraints of more than 767 bytes total
(user + record + tag). Since the tag can contain 3-byte Unicode characters,
it's limited to allow Unicode strings of the max length:
C{select floor((767 - sum(
case data_type
when 'tinyint' then 1
when 'smallint' then 2
when 'mediumint' then 3
when 'int' then 4
when 'bigint' then 5
end)) / 3)
from information_schema.columns
where table_name = 'tagTAG' and
column_name in ('id_bibrec', 'id_user')
;}
Using utf8_bin collation to treat tags as case and umlaut sensitive. I.e., treat
'uber', 'über', 'Über' and 'UBER' as four different tags."""
## MySQL (as of version 5.4) only supports the Basic Multilingual Plane (BMP)
## of Unicode Version 3.0, i.e., up to code point U+FFFF.
