This is a technical post about tand its databases.
Many Twproject customers use MySQL as database for their data; Twproject as web application supports UTF-8, which means that you can insert data in practically any language; but of course to save such data you need support along the “entire trip”, so your database must support UTF-8 data too. Now unfortunately MySQL default encoding is not UTF-8, but we found a way to work around that, which will be released with version 4.2: the Hibernate schema script generator will create UTF-8 encoding tables, as UTF-8 is supported also at table level (supported by MySQL 5), so it will work in all cases.
This is done by simply extending the Hibernate MySQL5InnoDBDialect with
@Override
public String getTableTypeString() {
return ” ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE utf8_general_ci”;
}
as suggested here.
Remember to use MySQL 5 with referential integrity on and to end you JDBC url with “?useUnicode=true&characterEncoding=UTF-8”!
This is particularly important for our future Chinese customers, now that a Chinese translation is forthcoming.
