Please clearly and accurately describe the problem scenario, desired behavior, and background information to facilitate timely follow-up by the product team.
[Problem Scenario Involved in the Requirement]
PingCAP has already established an office in Tokyo, and many enterprises have started to engage with and use TiDB.

Will there be support for localized character sets, such as sjis (Shift-JIS Japanese) collations?

If there are no localized character sets, we can only use utf8.
