From MariaDB 10.6.1, the utf8* collations listed above are renamed utf8mb3*.

Case Sensitivity

A 'ci' at the end of a collation name indicates the collation is case insensitive. A 'cs' at the end of a collation name indicates the collation is case sensitive.

NO PAD Collations

Until MariaDB 10.1, all collations were of type PADSPACE. From MariaDB 10.2, 88 new NO PAD collations are available. NO PAD collations regard trailing spaces as normal characters. You can get a list of all of these by querying the Information Schema COLLATIONS Table as follows:

SELECT collation_name FROM information_schema.COLLATIONS
WHERE collation_name LIKE "%nopad%";  
+------------------------------+
| collation_name               |
+------------------------------+
| big5_chinese_nopad_ci        |
| big5_nopad_bin               |
...

Accent Insensitivity

An accent insensitive collation is one where the accented and unaccented versions of a letter are considered to be identical for sorting purposes.

MariaDB 10.10 added the accent insensitivity flag, and new collations are marked with '_ai' or '_as' in the name to indicate this, for example:

...
| uca1400_spanish2_ai_ci         |
| uca1400_spanish2_ai_cs         |
| uca1400_spanish2_as_ci         |
| uca1400_spanish2_as_cs         |
...

Changes

• MariaDB 10.10 added 184 UCA-14.0.0 collations. Unicode-14.0.0 was released in September 2021. They contain 939 built-in contractions. Old collations based on UCA-4.0.0 and UCA-5.2.0 did not support built-in contractions. This is a step towards better Unicode Collation Algorithm compliance. With built-in contractions, some languages (e.g. Thai) won't need specific collations and will just work with the default "root" collation.
• MariaDB 10.6.1 changed the utf8 character set by default to be an alias for utf8mb3 rather than the other way around. It can be set to imply utf8mb4 by changing the value of the old_mode system variable.
• MariaDB 10.2.2 added 88 NO PAD collations.
• MariaDB 10.1.15 added the utf8_thai_520_w2, utf8mb4_thai_520_w2, ucs2_thai_520_w2, utf16_thai_520_w2 and utf32_thai_520_w2 collations.
• MariaDB 10.0.7 added the utf8_myanmar_ci, ucs2_myanmar_ci, utf8mb4_myanmar_ci, utf16_myanmar_ci and utf32_myanmar_ci collations.
• MariaDB 10.0.5 added the utf8_german2_ci, utf8mb4_german2_ci, ucs2_german2_ci, utf16_german2_ci and utf32_german2_ci collations.
• MariaDB 5.1.41 added a Croatian collation patch from Alexander Barkov to fix some problems with the Croatian character set and LIKE queries. This patch added utf8_croatian_ci and ucs2_croatian_ci collations to MariaDB.
