SharePoint has a small number of built-in permission levels, or role definitions as they are called code-wise. Several of these are easy to access through the SPRoleType enum.
However, the publishing features create new permission levels that are not found in SPRoleType. Although they can be accessed using code such as web.RoleDefinitions["Approve"], this requires hardcoded strings, and is not practical in a localized setting. Luckily, there is a way to access the localization of these permission levels. I got the solution from Alexey Sadomov, and present it here in a slightly modified form.
