(s)printf width and utf-8

[monkhandle]

Is this proper behaviour of printf family functions:

printf("'%4s'","€");

output:

' €'

Shouldn't output be

'   €'

? It seems as if all bytes (3 for euro symbol) were counted as visible field width.

The Euro symbol isn't one of the 127 ASCII characters. It is a multibyte character. You have a choice of using mulitbyte or wide characters. With wide characters, it would be

wsprintf (L"%4s", L"€");

 

[monkhandle]

That doesn't work, but:

wprintf(L"'%4S'",L"€");

outputs:

'   EUR'

Probably locales are not set properly. But still, why € symbol is output correctly with printf then ?
