Upload | Different | There can be several symbolic names with different casing. | An uploaded translation overwrites the existing translation. Any case-sensitive references to the old symbolic name will be broken. A warning message appears. |
Manual typing | Different | A new symbolic name with the case as typed is created. Its translations are independent of other symbolic names that only differ in case. | The symbolic name is automatically adapted to the already existing case, to not break case-sensitive references. Existing translations are automatically used. |
