Answer 1

来自苏格兰的麦克唐纳先生更喜欢这个名字，而爱尔兰的麦克唐纳先生更喜欢这样。如果事先不知道你指的是哪个绅士，就很难知道哪个是“正确的”，这需要更多的背景而不仅仅是文件中的文字。

此外，英国广播公司（或英国广播公司？）已经采取拼写一些名称，如美国国家航空航天局和北约。它刺激我;我非常不喜欢它。但这就是他们这些天所做的事情。什么时候丙烯酸（或某些人更喜欢称之为“初始主义”）本身就成了一个词？

Answer 2

这是一个黑客攻击，您可以存储要保持大写的首字母缩略词列表，然后将字符串中的单词与$exceptions列表进行比较。 虽然Jonathan是正确的，如果你的名字是你的名字而不是首字母缩略词，那么这个解决方案是无用的。但显然如果来自苏格兰的麦克唐纳先生处于正确的情况，那么它就不会改变。

was using her IBM computer to watch a ripped tv show from the BBC,
she was being watched by the FBI, Those little rascals were
