How can I set UTF8 and start H2O Flow UI via R?

I would like to set UTF8 in H2O Flow UI.

In terminal, I can set UTF8 and open H2O Flow UI.

java -jar -Dfile.encoding=UTF-8 h2o.jar

but I normally use R. How can I set UTF8 and start H2O Flow UI via R?

I tried that following.

options(encoding = "utf-8")
h2o.init()

and

h2o.init(extra_classpath = "-Dfile.encoding=UTF-8")

It runs, but doesn't set UTF8

Solution

  • Pass your option to the jvm_custom_args argument, not extra_classpath, as in h2o.init(jvm_custom_args = "-Dfile.encoding=UTF-8")
