What is the Linux equivalent of: MultiByteToWideChar & WideCharToMultiByte?

Question

I am working with a class that wraps the std::wstring, this code needs to be cross platform, are there equivalents to the windows functions: MultiByteToWideChar & WideCharToMultiByte on linux?

Thank you.

Answer 1

The Linux equivalents are the iconv functions iconv_open , iconv and iconv_close (say man 3 iconv_open etc. for the documentation). For cross-platform applications, use dedicated libraries such as ICU instead. Such libraries already contain their own string classes; there is no need to wrap std::wstring .

Answer 2

mbtowc和wctomb是最直接的等价物，但请注意它们对应于当前LC_CTYPE语言环境（可以使用setlocale()更改setlocale()的多字节字符集进行操作。
