I have a situation where I need to create some HTML on the fly and save it to a file, then turn around and have WebKit read the file using a file:// URL. (Why? NDA until the 29th.)
If I give WebKit the straight string, it handles any UTF-8 characters just fine.
However, when I save to a file (using NSString writeToFile:atomically), it doesn't save as UTF-8 and when the file is read I get all kinds of bogus characters.
Ahem:
writeToFile:atomically:
<x-tad-bigger>- (BOOL)writeToFile:(NSString *)</x-tad-bigger><x-tad-bigger>path</x-tad-bigger><x-tad-bigger> atomically:(BOOL)</x-tad-bigger><x-tad-bigger>flag
</x-tad-bigger>Writes the contents of the receiver to the file specified by path. path is written in the default C-string encoding if possible (that is, if no information would be lost), in the Unicode encoding otherwise.
I don't know about you, but I kind of want to know exactly what's getting written before I start. In any case, neither of those choices is UTF-8.
Try writing directly what's pointed by the pointer returned by - UTF8String, or putting that into an NSData and using its writeToFile:atomically: method.
Also:
Can someone point me in the right direction to be able to save the HTML string as a UTF-8 encoded file?
1) Do you start the file with a BOM? (Check unicode.org to be sure, but I think it's 0xEF 0xBB 0xBF.)
2) Does your HTML have an encoding tag? ("charset=utf-8" in a meta tag)
HTH,
