+## Setting up GHCJS on Windows
+
+If `stack setup` command fails to successfully complete with message: `commitBuffer: invalid argument (invalid character)`, it means you have a locale problem.
+This problem is not exclusive to GHCJS, and might happen also during other builds. A workaround is to set _Language for non-Unicode programs_ to _English (US)_.
+For details see [stack issue #1448](https://github.com/commercialhaskell/stack/issues/1448).
