问题 I have the following code on Linux:- rc = iconv_open("WCHAR_T", SourceCode); prior to using iconv to convert the data into a wide character string ( wchar_t ). I am trying to understand what it achieves in order to port it to a platform where the option on parameter 1, "WCHAR_T" , does not exist. This leads to sub-questions such as: Is there a single representation of wchar_t on Linux? What codepage does this use? I imagine maybe UTF-32 Does it rely on any locale settings to achieve this? I'm

问题 In my web app, I use a mailto link to open the outlook 2007. I also insert a url into the body. The problem is I need the whole url to be a hyperlink. If there is any spaces, then the hyperlink breaks, or even if there is any special characters like if it ends with a close parenthesizes the character wont be included in the hyperlink, so the link breaks. What I tried was using encodeURIComponent on the link, which url encodes it, but the issue is that in outlook, it will automatically decode

问题 I understand that std::codecvt<char16_t, char> in C++11 performs conversion between UTF-16 and UTF-8, and std::codecvt<char32_t, char> performs conversion between UTF-32 and UTF-8. Is it possible to convert between, say, UTF-8 and ISO 8859-1? Consider: const char* s = "\u00C0"; If I print this string and my terminal's encoding is set to UTF-8, I will see the character À . If I set my terminal's encoding to ISO 8859-1, however, printing that string will not print out the desired character. How
