I have a txt file of an conversation exported from WhatsApp. WhatsApp supports emoticons in their conversation, and the exported conversation also, to my surprise, contains these emoticons! That is, if I open the text file in a text editor (Text Wrangler on Mac 10.8) I can see the emoticons. The text file is encoded in UTF-8 and there are no resources associated with the file that I can tell.

That wouldn't be hard normally but I want the two keys corresponding to the two options to be space and enter.

My data has many HTML entities in it ( • ...etc) including &apos; . I just want to convert it to its character equivalent. I assumed htmlspecialchars_decode() would work, but - no luck. Thoughts? I tried this: echo htmlspecialchars_decode('They&apos;re here.'); But it returns: They&apos;re here. Edit: I've also tried html_entity_decode(), but it doesn't seem to work: echo html_entity_decode('They&apos;re here.') also returns: They&apos;re here.
