Param value encoding

Question

I have a benchmark in sbt-jmh, which is a "wrapper" for jmh for which I have a parameter that contains non-ASCII characters. It looks like this:

@Param(Array("1000", "１000"))

That's the equivalent for Java

@Param({"1000", "１000"})

Note that the second string "１000" starts with a full width one character, code point +uFF11

This file is encoded in UTF8. My platform is Windows 8.1, and the platform encoding is cp1252

My build.sbt contains scalacOptions ++= List("encoding", "UTF8")

I expect very similar benchmark results for both params, but I'm seeing drastically different results, that seem to imply that the second string isn't processed properly.

How can I make sure the benchmark uses the correct string as a parameter?

This was a bug in 1.17, and is fixed in 1.18
