Here’s a little Scala method I wrote to replace some “bad” characters that won’t print properly on my Radio Pi display:
def replaceBadCharacters(s: String): String = { s.replaceAll("“", "\"") .replaceAll("”", "\"") .replaceAll("‘", "\"") .replaceAll("’", "\"") }
There are other ways to solve this problem, but I threw this together as a quick patch until I can figure out why the Phosphor screen saver on the Raspberry Pi won’t print those characters that I’m replacing.
