wchar

问题 I have a python (3.6) code that should pass a Unicode string to an Unreal Engine project. The Unreal Engine displays text in TEXT format which I'm not wrong is an array of Win-Api's TCHARs. I saw that on my platform the TCHAR is 2 bytes. Here is how I encode the string on the python side: by = bytes(st, 'utf-8') I tried encoding and passing the string "Hello" . The unreal got the data ['H', 'e', 'l', 'l', 'o'] (each char 1 byte), and printed "效汬o" (it treats the "He" and "ll" as a single

问题 I am on a Linux system and set the keyboard setting to UK in order to capture and print out a UK pound symbol (£). Here is my code: #include <stdio.h> #include <wchar.h> #include <locale.h> int main () { wint_t wc; fputws (L"Enter text:\n", stdout); setlocale(LC_ALL, ""); do { wc=getwchar(); wprintf(L"wc = %lc %d 0x%x\n", wc, wc, wc); } while (wc != -1); return 0; } Also, I wanted to store the UK pound symbol (£) as part of a string. I've found that std::string does NOT indicate an accurate

问题 While going through the file wchar.h on Mac OS X system, I found that wchar_t equivalent of str functions such as wcscpy, wcscat are poisoned when __cplusplust is not defined and max size of wchar_t is of 2 bytes (by using compiler option -fshort-wchar). It seems that for C program, it does not allow such functions to use if -fshort-wchar is defined. I would like to know that what is the implication of using wchar_t functions when -fshort-wchar is used? You may wonder that why I need to use

问题 My C program is pasted below. In bash, the program print "char is ", Ω is not printed. My locale are all en_US.utf8. #include <stdio.h> #include <wchar.h> #include <stdlib.h> int main() { int r; wchar_t myChar1 = L'Ω'; r = wprintf(L"char is %c\n", myChar1); } 回答1: This was quite interesting. Apparently the compiler translates the omega from UTF-8 to UNICODE but somehow the libc messes it up. First of all: the %c -format specifier expects a char (even in the wprintf-version) so you have to

I have a mistake in the function for reading the file but I don't know what is wrong. all the symbols are read correctly when the symbol is beyond the ASCII table. while ((c = fgetwc(file)) != WEOF) { if (c != L'\n') { if (i == buf_length) { buf_length += BUF; wchar_t *rebuf = realloc(tmp, buf_length * sizeof

Why do I get numbers as output result when using wchar_t? #include <iostream> using namespace std; int main() { wchar_t q; q = 'A'; cout << q; q = 'B'; cout << q; q = 'C'; cout << q; return 0; } 回答1: The

问题 According to some older StackOverflow questions ( Unable to pass std::wstring across DLL , C++ DLL returning pointer to std::list<std::wstring> ) it's not considered safe for a C++ DLL to return a std::wstring because there's no guarantee the main program has the same definition of std::wstring and therefore it might cause a crash. However, in http://en.cppreference.com/w/cpp/string/basic_string , it seems std::wstring can be used interchangeably with a WCHAR array now: (Since C++11) The
