• How to convert map to url query string?

I know I can easily write it myself, I am just surprised that I cannot find it anywhere (I checked Apache Commons so far).

• Outputing UTF-8 string on Mac OS's Terminal

  - by SuperBloup

  I got a programm in haskell outputting utf-8 using the package utf8-string and using only the output functions of this package. I set the encoding of each file I write to this way : hSetEncoding myFile utf8 {- myFile may be stdout -} but when I try to output : alpha = [fromEnum 0x03B1] {- a -} instead of the nice alpha letter I got on Linux (or in a file on windows), I got the following : α The weird thing is even if I try to write the output on a file, I can't read it back with mvim as an utf-8 file.

• Does -localizedDescription of NSError return the actual localized string, or does it return a key fo

  - by mystify

  Must I do something like this? NSString *errorDescription = [error localizedDescription]; NSString *errorInfoStr = NSLocalizedString(errorDescription, nil); Or do I use NSLocalizedString already when populating the userInfo dictionary with the NSLocalizedDescriptionKey key and value? So the value for that is not actually a key for NSLocalizedString, but it is the actual localized string ready to show up on screen?

  - by ITg

  I need to use preg_match to check that only a-z0-9. is used (including full stop(.)). I don't want to replace anything. My problem is that it doesn't notice white space at beginning of a string.
