Continuing the conversation from #53:

@swift-kim, @bbrto21, I have run a .NET app on my TM1 and got the error in the dlog:

I/DOTNET_LAUNCHER(13337): xkbcommon: ERROR: couldn't find a Compose file for locale "pl_PL.UTF-8"

The log does not appear when I run native or web apps, so it seems to be a problem with .NET runtime.
I guess, we should just report it to the .NET runtime team - what do you think about it?

[swift-kim]

I'm part of the .NET runtime team. I'll ask one of my colleagues first. 😉

I submitted an error report: https://github.sec.samsung.net/dotnet/home/issues/403 (intenal GitHub)

We may filter out this error message by simply adding a filter in the log reader. 😎

It seems that this is no longer an issue we need to handle. how about closing this issue?

flutter-tizen/flutter-tizen#131 work arounds this issue.

We have received the following message about this behavior, from C# runtime team:

Actually if there is no 'pl.PL.UTF-8' found in system, it should be displayed as it can be important information in some cases. Please note that "pl _ PL.UTF-8" is not the locale available on any system.

E/ConsoleMessage(24758): xkbcommon: ERROR: couldn't find a Compose file for locale "pl_PL.UTF-8"

Anyway, the error message you mentioned is sometimes perceived as an error by some developer(s)/tester(s).
Thus, I removed the error message from libxkbcommon package only if the locale has not been set to 'en_US.UTF-8'.
FYI, we only use 'en_US.UTF-8' as a primary locale for key mapping for UI app(s) in Tizen.

A patch for this problem has already been merged to xkbcommon.

@swift-kim, it seems, that the problem has been fixed in xkbcommon, so I close this issue as @bbrto21 suggests ;)
