When `unicode_usernames` is enabled and the default locale is non-English, `Jobs…::EnsureDbConsistency` renames automatic groups to localized Unicode names (e.g., "admins" → "管理员"). Visiting the group's assigned topics page then triggers a 500 error (`URI::InvalidComponentError`) because the Unicode group name isn't properly encoded when building pagination URLs. The encoding of route params affected by `unicode_usernames` was scattered across multiple places: - `:username` was encoded in `page_params` - `:group_name` was encoded in `construct_url_with` - `:groupname` (assign plugin) was not encoded anywhere → 500 error This consolidates all encoding into `construct_url_with`: - `page_params` now passes raw values for all route params (`:username`, `:group_name`, `:groupname`, `:period`) via a single loop - `construct_url_with` encodes all three Unicode-sensitive params (`:username`, `:group_name`, `:groupname`) in both `page_params` and `opts` when `unicode_usernames` is enabled - The unencode block now uses simple string splitting instead of `URI.parse`, which cannot handle Unicode characters in paths https://meta.discourse.org/t/396092
