转换字母（devnagari转换为英文）时出现索引列表问题

我目前正试图用英文字母映射devnagari脚本。但偶尔偶尔遇到列表索引超出范围。我不想错过任何名单。这就是为什么我不想使用错误处理，除非有必要。你可以看看我的脚本，并帮助解释为什么会出现这种错误？在我的word文件中我找到了哪个单词导致了错误，但是如果我从这个单词中上下使用了两个句子，那么错误就不存在了。即我认为错误发生在特定的字符串长度。转换字母（devnagari转换为英文）时出现索引列表问题

删除代码中的所有不必要的注释，运行代码并向我们提供完整的堆栈跟踪，以便我们提供帮助。 – thefourtheye

@thefourtheye当然。完成了！ – choman

问题与一些Unicode字符躺在我正在测试它的文件。它在删除它们之后运行。
