Getting errors when setting a wstring to a Hebrew string literal in Code Blocks

Question

I'm using Code Blocks to write a C++ program. I want to put a Hebrew string in an std::wstring type, but it isn't working.

If I write this:

std::wstring str2("שלום");

and compile, it gives me this error:

error: no matching function for call to 'std::basic_string<wchar_t>::basic_string(const char [5])'|

If I use "L" before the string literal, i.e.

std::wstring str2(L"שלום");

then it gives the error:

error: converting to execution character set: Invalid argument|

If you used the L to indicate that it's a wchat_t, did you include ? — FrankS101, Feb 19 '17 at 13:56

Don't use non-ascii strings in the source of your program, it is not portable, implementation-dependent and a bad practice anyway. Having said that, what encoding is used in your source file? — n. m. could be an AI, Feb 19 '17 at 14:05
i dont know what encoding i use, i use code block and compiler GNU GCC — רועי נוה, Feb 19 '17 at 14:33
What are the 16 bit values in unicode that correspond to those characters? What is your runtime encoding of `wchar_t` strings at the point of use? (I hope unicode! Utf-32? Utf-16? Ucs-2?) You can probably put escape sequences into the `L""` string and have it work. — Yakk - Adam Nevraumont, Feb 19 '17 at 15:18

Wide string literals have the form L"peace". The leading L is what tells the compiler it's a wchar_t instead of char.

i got it.

i use L before like: str2 (L"שלום");

Set up CodeBlocks editor by clicking Settings then Editor then Encoding settings, and select UTF-8. You probably want to select "As default encoding" and unselect everything else. You won't have to pass -finput-charset to the compiler because UTF-8 is the default

Don't use iso-8859-8. Use UTF-8 like 99% of the world. Set up CodeBlocks editor by clicking Settings then Editor then Encoding settings, and select UTF-8. You probably want to select "As default encoding" and unselect everything else. You won't have to pass -finput-charset to the compiler because UTF-8 is the default. – n. m. could be an AI Feb 20 '17 at 08:03
אתה תמיד מוזמן. Also please read [this](https://www.joelonsoftware.com/2003/10/08/the-absolute-minimum-every-software-developer-absolutely-positively-must-know-about-unicode-and-character-sets-no-excuses/) – n. m. could be an AI Feb 20 '17 at 09:51
@רועינוה: If you've accepted the suggestion to use UTF-8, please amend your answer accordingly. Recommending the use of iso-8859-8 really is a bad idea. – einpoklum Mar 11 '17 at 22:52
