Mojibake in Media section of about:support Steps To Reproduce: 1. Using Nightly 56.0a1 en-US build on Windows10 1703 Japanese Edition 2. Open about:support Actual Results: Mojibake in Device neme. See attached screenshot
Chun-Min, want to have a look ?
Component: Untriaged → Audio/Video
Product: Firefox → Core
Nightly 56.0a1 ja build is also affected. So, It seems to happen regardless of the localization build.
I guess the reason is using NS_ConvertASCIItoUTF16. The friendly_name, group_id of cubeb_device_info is converted to UTF8 on Windows but NS_ConvertASCIItoUTF16 will mangle any non-ASCII string into a meaningless UTF-16 string. Replacing NS_ConvertASCIItoUTF16 with NS_ConvertUTF8toUTF16 should solve it, but we need to make sure the friendly_name, group_id, vendoer_name are also UTF8 in other backends.  https://searchfox.org/mozilla-central/rev/09c065976fd4f18d4ad764d7cb4bbc684bf56714/dom/media/CubebUtils.cpp#613-615  https://searchfox.org/mozilla-central/rev/09c065976fd4f18d4ad764d7cb4bbc684bf56714/media/libcubeb/src/cubeb_wasapi.cpp#2202,2213  https://developer.mozilla.org/en-US/docs/Mozilla/Tech/XPCOM/Guide/Internal_strings#ASCII_to_UTF-16_converters

Comment on attachment 8891270 [details] Bug 1384944 - Replace NS_ConvertASCIItoUTF16 by NS_ConvertUTF8toUTF16; Approval Request Comment [Feature/Bug causing the regression]: Bug 1197045 [User impact if declined]: when running Firefox on a platform with a locale that uses characters that are not in the ASCII set, audio devices names are showing up garbled. [Is this code covered by automated tests?]: No. [Has the fix been verified in Nightly?]: Yes, in this bug and in bug 1391162 (that prompted for this uplift request). [Needs manual test from QE? If yes, steps to reproduce]: I think we're pretty confident here. If needed in  are steps to manually verify this patch. [List of other uplifts needed for the feature/fix]: None. [Is the change risky?]: No. [Why is the change risky/not risky?]: The fix is tiny, and the cause is well understood. Multiple people have provided independent verification, in multiple locales, on multiple OS versions. [String changes made/needed]: None
