Jack compiler seems to ignore encoding compile option

I recently upgraded an Android project to use use the Jack compiler:

jackOptions {
  enabled true
}

It uses box-drawing characters that are embedded in source files as string literals. Everything was fine pre-Jack. I used:

compileOptions {
  encoding "UTF-8"
  // {snip}
}

and the box drawing characters appeared at runtime. After upgrading to Jack, it renders as corrupted Unicode-interpreted-as-ASCII (?): â”, instead of │

I can work around this by using Unicode escapes (\u2502), but it's a bit odd that a brand new compiler for Java doesn't support Unicode... Is there another option that Jack recognizes to accept UTF-8 encoded source files?

  • This appears to be a known issue with the current release of jackjill
