Fails on all chromecast devices

 [ RUN      ] FileUtilTest.OpenFileNoInheritance
../../base/files/file_util_unittest.cc:1751: Failure
Expected: (nullptr) != (file), actual: 4-byte object <00-00 00-00> vs NULL
Google Test trace:
../../base/files/file_util_unittest.cc:1748: r,ccs=UNICODE
[  FAILED  ] FileUtilTest.OpenFileNoInheritance (1 ms)

Added some extra log info:
INFO:file_util_posix.cc(745)] result: 0xb8f2fc60, errno: 0, filename: /tmp/.org.chromium.Chromium.SmP2Az/a_file, mode: wbe, LC_CTYPE: C

INFO:file_util_posix.cc(745)] result: 0, errno: 22, filename: /tmp/.org.chromium.Chromium.SmP2Az/a_file, mode: re,ccs=UNICODE, LC_CTYPE: C


Also tried a few other variations:

ccs=UTF-8 passes
errno: 0, filename: /tmp/.org.chromium.Chromium.K8LMEs/a_file, mode: re,ccs=UTF-8

UTF-16 and UTF-16LE both fail
 errno: 22, filename: /tmp/.org.chromium.Chromium.8XVvMm/a_file, mode: re,ccs=UTF-16LE
errno: 22, filename: /tmp/.org.chromium.Chromium.HOb9jk/a_file, mode: re,ccs=UTF-16

Does this test need to use ccs=UNICODE, or can it be changed to use ccs=UTF-8 so it will pass on chromecast devices?
