斯卡拉 : Enumeration with special characters

Question

如何创建和使用其值中包含一些特殊字符和空格的枚举？

object Bots extends Enumeration {
  type Bots = Value
  val `apis-google`, `mediapartners-google`, `adsbot-google-mobile-apps`, `google favicon` = Value
}

当调用这个枚举时，特殊字符似乎被一些内部标识符替换或改变了它们的编码:

for (bot <- Bots.values) println(bot)

输出:

apis$minusgoogle 
mediapartners$minusgoogle 
adsbot$minusgoogle$minusmobile$minusapps 
google$u0020favicon

编辑:我使用 scala 2.2
