I have user submitted tags that can be any type of (valid) UTF-8 string. I want to know if it is safe to include them in the URL merly by running them through urlencode().

In other words, is urlencode() safe to use for valid UTF-8 strings? (by valid I mean id have already force-encoded them to UTF-8)

How can I tell if a CSV is in UTF-7 or UTF-8

as seen on Stack Overflow - Search for 'Stack Overflow'
Excel seems to save CSV files in (what I think is) UTF-7, despite the fact that most information I have read suggest that in general, you should not UTF-7. Indeed, other applications (Text pad, which lets me choose) save things in UTF-8 (or Unicode etc, but UTF-7 is not even an option). Using .NET… >>> More
