Cannot convert name to ASCII

See original GitHub issue

I’m hit by an issue where node-gyp fails when rebuilding java bindings. Tried various different versions of node-gyp, but the issue remains. Strangely it only fails inside the official node-docker images. Locally on my Macbook

Node: 7.10.0 (official docker image)

error /opt/app/node_modules/java: Command failed.
Exit code: 7
Command: sh
Arguments: -c node-gyp rebuild
Directory: /opt/app/node_modules/java
Output:
gyp info it worked if it ends with ok
gyp info using node-gyp@3.6.1
gyp info using node@7.10.0 | linux | x64
