libu8 is a portability and utility library written in modern C for Unix-based platforms. libu8 is licensed under the LGPL (V2.1) and GPL (V2) you can find the source on github. Detailed robodocs are available (generated by Doxygen).

libu8 provides:

• string utilities for portably working with UTF-8 encodings and converting to and from a wide variety of other text encodings;

• stream-based text I/O using UTF-8 internally but supporting automatic conversion to and from other encodings;

• an extensible printf (u8_printf) function including output to strings;

• extensible and customizable logging functions (using u8_printf);

• wrappers for time-related functions allowing fine-grained times and specification of arbitrary time zones;

• an exception handling library using setjmp/longjmp with unwinds and dynamic error catching;

• signal handlers for turning signals into exceptions;

• a client networking library for socket io, connection pools, and simple hostname lookup;

• a server networking library for lightweight multi-threaded high-performance server implementation;

• various hash and digest functions, including MD5, Google's cityhash, and various SHAx functions;

• cryptographic function wrappers using local libraries;

• a variety of file or URI path manipulation functions;

• a wrapper for rusage() resource system calls;

• wrappers for accessing file and directory contents and metadata;

• support for lookup up and interpretation of named character entities;

libu8 is especially intended for software which uses UTF-8 internally but may interact with applications and services employing different character encodings. However, it has grown to provide a variety of other portable functions.
