refactor: change regex of project to allow unicode except any whitespace

[lizable]

This PR resolves #1658. Before this PR every client-side got "400 Bad Request" error, which is originated from regex that only allows alphanumeric characters,-(hyphen) and _(underscore). After applying this PR will allow unicode characters, such as Korean(e.g. "프로젝트"), But not allowing any whitespaces.
