How do you fix Hebrew that sits inside a nested XREF?

Sometimes the DWG you received itself refers to further external files (XREFs), and the broken text is in those. Make sure the XREF files are where the main DWG expects to find them: the fix also goes through the XREFs inside the link, at any depth, and fixes the Hebrew in all of them.

To hide or show nested XREFs in the active view, use "Edit XREF". It changes how Revit displays the link, and the DWG file does not change. "Reset XREF" returns the earlier state.
