Question

I looked hours to solve this issue, and found nothing. Sorry if answer is somewhere on Internet, I really couldn’t find it.

I have a NSString *header = @"ästrç"; or with any other umlauts from German, Swedish, etc languages.

I need this NSString converted to:

const char* cString = [header cStringUsingEncoding: NSASCIIStringEncoding];

Note: NSASCIIStringEncoding, NSMacOSRomanStringEncoding not working.

I also tried this:

const char *cString = [header UTF8String];

Not working.

Can someone help me please? This is very strange.

EDIT:

By “not working” I mean that if I have these chars:

It will output this:

I don’t care of NSLog. I need that const char * for a method to write in PDF:

HPDF_Page_TextOut  (HPDF_Page    page, HPDF_REAL    xpos, HPDF_REAL    ypos, const char  *text)

const char *cString = [header UTF8String] will work, but you are probably testing it with
NSLog("%s, cString);.

NSLog will not work, because %s is expecting ASCII string not UTF-8.

Details: convert NSString to const char *.
