Anonymous created an issue 2014-09-27 If you have unicode in your window titles, --dump-samples fails example window name which causes problems WM_NAME(COMPOUND_TEXT) = "gwern \033%G\342\200\223\033%@ Konversation"
I have the same issue, too. It is a Windows 10 machine. The issue only appears, when running from cmd.exe. If I use "Bash on Ubuntu on Windows" the error does not appear. I am not entirely sure, if this is due to unicode (as none is seen in the output) or if there is another problem.
The command fails like this:
C:\Users\<user redacted>>arbtt-stats --dump-samples --filter="$sampleage <02:00" 2018-07-09 21:46:38 (5688ms inactive): ( ) \Device\HarddiskVolume6\Windows\explorer.exe: Program Manager ( ) \Device\HarddiskVolume6\Windows\SystemApps\Microsoft.Windows.PeopleExperienceHost_cw5n1h2txyewy\PeopleExperienceHost.exe: arbtt-stats: <stdout>: commitBuffer: invalid argument (invalid character)
