UTF-16 “.strings” Files
For years, we’ve followed Apple’s documented recommendation that .strings files should be saved in UTF-16 format […] But this has caused so many headaches, that I finally decided it’s time to defy this recommendation, and go UTF-8 for our .strings files.
Xcode now converts strings files to UTF-16 when building a project, so I now store them in UTF-8, which works better with version control and other tools.
