Does this matter (much)? Often non 0027 apostrophe's won't have special meaning anyway. Even if they do have special meaning, escaping of many sequences is required for numerous scripting languages?
I mean that I could see the theoretical problem, eg: using Windows WideCharToMultiByte() with best fit mappings enabled, but that particular example is broken in lots of ways. For example, I could also imagine internally escaping 0027 as U0027. Then if I found a URL with "U0027" in it, I could end up doing something unexpected.
