• A brief description

Japanese character output in Integrated Terminal of Visual Studio Code causes the next prompt out of position after upgrading to Creators Update. This issue is reproducible 100%.

For example, echo あ causes the next prompt out of position. The screenshot below is the result of ls -la with en only, and echo あ. ls -la does not cause any problem, but echo あ causes the next prompt out of position.

• Expected results

Japanese character output in Integrated Terminal of Visual Studio Code keeps the next prompt in the correct position.

• Actual results (with terminal output if applicable)

Japanese character output in Integrated Terminal of Visual Studio Code causes the next prompt out of position.

• Your Windows build number

Version 1703, build 15063.13 (Japanese)

• Steps / All commands required to reproduce the error from a brand new installation

1. Install Windows 10 Creators Update
2. Install BoW on Creators Update
3. Install Visual Studio Code (v1.11.1)
4. Open BoW in Integrated Terminal by [Ctrl] +[@]
5. Run echo あ
   -> This causes the next prompt out of position.

• Other troubleshooting

I tried repro on the following three environment by Visual Studio Code v1.11.1. By this results, this does not seem to depend on Visual Studio Code, but Creators Update. Can't BoW handle this issue?

1. OK
   OS: build 14393.0
   BoW: Ubuntu 14.04

2. NG
   OS: build 15063.13 (upgraded from build 14393.0)
   BoW: Ubuntu 14.04 (not upgraded)

3. NG
   OS: build 15063.13
   BoW: Ubuntu 16.04

Copied from original issue: Microsoft/WSL#1871

Start by reproducing the issue in the Integrated Terminal with BoW on Windows 10 build 15063.13, running echo あ after the listed installation steps, and compare it with build 14393. No source file or test is named; done means the next prompt remains correctly positioned after Japanese output, including the reported Creators Update environments.
