Localization package failed to create assets due to inconsistent Windows drive letter casing in path variables

Localization Package Version: 1.5.3
Issue: Unable to create localization assets (e.g., Locale Asset, String Table Collection Asset).

Cause:
The MakePathRelative method in the Localization package(PathHelper.cs) fails on Windows due to inconsistent drive letter casing between paths.

Code Reference:

internal static string MakePathRelative(string path)
{
    var dataPath = Application.dataPath;
    var root = dataPath.Substring(0, dataPath.Length - "Assets".Length);
    if (path.StartsWith(root))
    {
        path = path.Substring(root.Length);
    }

    return path;
}

Details:

  • Paths returned by EditorUtility.SaveFolderPanel use a lowercase drive letter (e.g., c:/UnityProjects/Sample/Assets/I18n), while Application.dataPath uses an uppercase drive letter (e.g., C:/UnityProjects/Sample/Assets).
  • This mismatch causes the path.StartsWith(root) check to fail, preventing the path from being converted to a relative path.
  • Since the path remains absolute, AssetDatabase.CreateAsset fails to create the specified assets.

My Fix:
I copied the Localization package to the Packages folder and modified the code as follows:

if (path.StartsWith(root, StringComparison.InvariantCultureIgnoreCase))

Question:

  • Is there a way to resolve this issue without modifying the package code directly?
  • Will this issue be addressed in a future release?
