## Description Currently, GitLab Runner only support UTF-8. This is rarely a problem with Linux. However, on Windows, if the system locale is set to specific non-English languages, the default character becomes something other than UTF-8. For example, in the case of Japanese, it will be Shift-JIS. As a result, Following issues happen: 1. Non-English messages contained in built-in commands of Windows OS will be garbled. {width="594" height="610"} 2. Commit messages created in GitLab UI (encoded in UTF-8) causes unexpected behavior in the Runner. (This can be replicated by this commit message: `日本語のコミットメッセージのテスト`) {width="697" height="632"} 3. If the characters in the message displayed by the user during the job process are encoded in non-UTF8, they will be garbled. {width="864" height="99"} (The "1" and "2" can be reproduced in `posershell`. No cases of reproduction have been found in `pwsh`. The "3" can be replicated in the both `powershell` and `pwsh`) ## Proposal * I would propose to add support for non-UTF8 character sets. * In the meantime, add the following to the document: “You need to set system locale to English.” * This can avoid the problems 1 and 2 above. ## Links to related issues and merge requests / references https://gitlab.com/gitlab-org/gitlab-runner/-/merge_requests/5473
