If you are working on a new translation of Camino 1.5.x, there are some .strings files that are UTF-16LE encoded, while the current version of AppleGlot only works properly with UTF-16BE files. In order to work around this problem, Wevah has written a perl script that will convert any .strings file it finds into UTF-16BE files. See Bug 382151 comment 7 for the script.
Run the script on the copy of Camino you will eventually place in _NewBase. After the files have been corrected, place that copy of Camino into your environment’s _NewBase folder and run the Initial Pass in AppleGlot.
(Bug 392918 will fix this problem permanently in time for Camino 1.6.)
