+## InvalidByteSequenceError
+
+Test pass locally but on CI there is an error with encoding.
+One of the possible solutions for error: `Encoding::InvalidByteSequenceError: "\xF0" on US-ASCII` during build is setting the correct locale in the build job:
+
+```
+export LC_CTYPE=en_US.UTF-8
+
+```
+
+or
+
+```
+export LANG=en_US.UTF-8
+```
