In any case, I will be happy to contribute a few test cases if you necessary for the fix(I am not familiar with Objective C so let me know what else I can be more helpful). These defaults for charsets are fixed (not overridable AFAIK.) But yes, it's tricky as you will have to look for database, table, column overrides first before you look for the charset defaults. PS: it's pretty easy to get the default collation for each charset, as shown in the documentation above. So opening this ticket and sharing what we discovered is our way to contribute to the community in the hope that it saves other people who baffle at the same issue. And to our surprised, Sequel Pro, being one of our most favorite tools, is showing us the wrong information should we have the right information, we'd have found out the issue sooner. That is, charset level default collations.

I don't blame you for this bug - it's really MySQL's messy unicode implementation and its own invention of convoluted utf8mb4 that's causing a lot of headaches in the first place.Ī little back story: I've been spending more than a month to figure out an emoji bug in our system that eventually leaded to this shocking discovery of MySQL's.

Getting Collation right matters, because string indexes are depending on thanks for looking into the code to determine the plan of action. In other words, whenever there is a charset override but without collation override, MySQL uses charset default collation instead of parent hierarchy's default collation (in my test case, charset default is utf8mb4_general_ci, parent hierarchy's default, which is database default is utf8mb4_unicode_ci). I believe Sequel Pro is missing the logic to figure out charset default. That is, charset override will override collations implicitly as well. Just a little FYI, MySQL determines collation based on 4 levels of defaults when there is no collation override. utf8, collation has been consistently wrong through the different versions - no ambiguity, just flat out wrong.

00 re: utf8mb4 is only officially supported starting with 1.1 - if you are officially supporting utf8mb4, which is different from utf8, then you should make a visually different display name to denote the full support of 4-byte Unicode code map since utf8 only supports <6% of what utf8mb4 supports.Īlso, regardless the of visual change to differentiate charsets between utf8mb4 vs. | emoji_test | CREATE DATABASE `emoji_test ` /*!40100 DEFAULT CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci */ | | created_at | datetime | NULL | YES | | NULL | | select,insert, update, references | | | txt_col | varchar( 255) | utf8mb4_general_ci | NO | | | | select,insert, update, references | | | id | int( 11) | NULL | NO | PRI | 0 | | select,insert, update, references | | | Field | Type | Collation | Null | Key | Default | Extra | Privileges | Comment | Mysql > show full columns from tbl_collate_utf8mb4_general_ci ) ENGINE =InnoDB DEFAULT CHARSET =utf8mb4 | `txt_col ` varchar( 255) NOT NULL DEFAULT ' ', | tbl_collate_utf8mb4_general_ci | CREATE TABLE `tbl_collate_utf8mb4_general_ci ` ( Mysql > show create table tbl_collate_utf8mb4_general_ci utf8 (broken UTF-8 unicode implementation as it only covers BMP, Plane 0 or about 5% of all UTF-8 characters). Sequel Pro still displays UTF-8 Unicode charset, which is indifferent from utf8, where it should have distinguish between utf8mb4 (correct UTF-8 unicode implementation) vs.

Charset on Table structure tab view doesn't recognize utf8mb4 - the 4-byte correct implementation of full utf-8 character code points.

But Sequel Pro displays the table level default collation utf8mb4_unicode_ci instead. In this case, middle_name, last_name, username all should have been overridden by column level charset utf8mb4, which has a default collation utf8mb4_general_ci. That is, I believe Sequel Pro assumes table level default collation rather than given charset's default collation as MySQL does.

Column level charset/collation override are NOT taken into consideration (or perhaps when overridden at columns, the defaults is not properly inferred as MySQL would).

Under Structure tab of the selected table, charset and collation are incorrectly displayed as pointed out below in RED boxes. ) ENGINE =InnoDB AUTO_INCREMENT = 3 DEFAULT CHARSET =utf8mb4 COLLATE =utf8mb4_unicode_ci `email ` varchar( 120) CHARACTER SET utf8mb4 NOT NULL, `username ` varchar( 100) CHARACTER SET utf8mb4 DEFAULT NULL, `last_name ` varchar( 40) CHARACTER SET utf8mb4 DEFAULT NULL, `middle_name ` varchar( 40) CHARACTER SET utf8mb4 DEFAULT NULL, `first_name ` varchar( 40) COLLATE utf8mb4_unicode_ci DEFAULT NULL,
