I like C++ but I realized that I keep implementing functionality that should be part of the standard library. Here are the features I'm missing most:

• an easy way to spawn a subprocess while controlling the standard input/output. something like popen but integrated with the standard I/O streams.
• UTF-8 and Unicode: convert between UTF-8, UTF-16, and UTF-32. convert a string to lower case and to upper case.
• networking: an easy way to implement a HTTP client or server
• cross-platform memory-mapped files
• thread-safe (and possibly lock-free) queues
• persistent data structures
• JSON serialization/deserialization

What are you missing most from the C++ standard library?
