Hello ,

I tried reproducing this with the method you gave but I’m not seeing any type of crash. To be exact, I did the following:

  1. Create a new project in 4.13.1
  2. Add a new blueprint based off of Actor and open it in the blueprint editor
  3. Use the Microsoft Language bar to switch to Chinese (Simplified, PRC), using the Chinese Simplified QuanPin version 6.0 keyboard (tried a few others as well)
  4. Right-click in the Event Graph and enter a few Chinese characters. Also tried the search bar under My Blueprint.
  5. Click elsewhere in the editor, such as on another tab, on another panel, and elsewhere.

Nothing special happened when I did this. Is there possibly something that I’m missing? Are you on a Chinese version of windows or on another language version? This could have impact on reproducing this.

Also, could you provide the callstack from the crash and your Machine ID from the Crash Reporter Window so that I can look up the crash?

Hi Matthew,

Mine crashes 100%. Look

I enter some random letters, then press mouse in blueprint field.
I use Microsoft Pinyin Keyboard. Windows 10 x64. Not chinese I believe.

Same crash occurs in shaders and in sound cue editor as well.

Here is stack trace of that event https://i.gyazo.com/b804edc3db6b87c8a7c6df5cca4ad075.png

Thank you for mentioning your OS version. It seems that this may only be related to the Windows 10 version of that Chinese Pinyin keyboard. I tried both of the Pinyin versions on Windows 7 but didn’t have any issues. As soon as I tried the Windows 10 one however, my editor crashed as well. I’m currently getting our latest build on that computer so that I can confirm that it’s still occurring there and then I’ll be placing a bug report in.

I’ve placed a bug report in for this issue after confirming that it continued to occur in our latest internal build. You can find the report here: UE-38073

Have a nice day!
