为什么这个javascript片段触发“意外令牌非法”

缩小的google-code-prettify javascript lib的一行触发了"意外令牌非法"。如果我删除它，库工作正常。我试图删除特殊的字符，期望编码是代码，但似乎不是。

PR.registerLangHandler(PR.createSimpleLexer([["pln",/^['t'n'r 'xa0'u2028'u2029]+/,null,"'t'n'r Â'xa0

我试图将["pun",/^(?:'[|])/]])更改为["pun",/^(?:'[|])/])但没有运气。

编辑：

我可以确定"''t'''r â''xa0†̈"©是它的因果关系，但我说不出为什么。
