I think an apostrophe is a better way of indicating to English speakers the way Danish treats an initial k, as in K'nuth. There's no actual vowel in there. Also it looks cooler, as in ph'nglui mglw'nafh K'nuth R'lyeh wgah'nagl fhtagn. Fits right in, doesn't it?
This is a thread where people can ask questions that they would ordinarily feel embarrassed for not knowing the answer to. The previous "stupid" questions thread went to over 800 comments in two and a half weeks, so I think it's time for a new one.
