Gnu iconv manual

This function is missing on some platforms: macOS , FreeBSD , OpenBSD , Minix , Cygwin , mingw, MSVC 14, Android , when GNU libiconv is not installed. For some encodings A and B, this function cannot convert directly from A to B, although an indirect conversion from A through UTF-8 to B is possible. The iconv Implementation in the GNU C Library. After reading about the problems of iconv implementations in the last section it is certainly good to note that the implementation in the GNU C Library has none of the problems mentioned above. What follows is a step-by-step analysis of the points raised above. The evaluation is based on the current state of the development (as of January ). There are three main implementations of iconv in use. Linux's C runtime glibc contains one. Several platforms supply GNU libiconv, including macOS, FreeBSD and Cygwin, in some cases with additional encodings. On Windows we use a version of Yukihiro Nakadaira's win_iconv, which is based on Windows' codepages. (We have added many encoding names for compatibility with other systems.).

A complete iconv example. The example below features a solution for a common problem. Given that one knows the internal encoding used by the system for wchar_t strings, one often is in the position to read text from a file and store it in wide character buffers. The iconv_open() function allocates a conversion descriptor suitable for converting byte sequences from character encoding fromcode to character encoding tocode. The values permitted for fromcode and tocode and the supported combinations are system-dependent. The complexities that AM_ICONV deals with are the following: Some operating systems have iconv in the C library, for example glibc. Some have it in a separate library libiconv, for example OSF/1 or FreeBSD. Regardless of the operating system, GNU libiconv might have been installed. In that case, it should be used instead of the operating system.

Dec Other implementations of iconv may also be extensible; see your local documentation if you're not using the GNU C library. More Information [top].
