<div dir="ltr">Just for posterity, a more general approach for converting NSString * or CFStringRef to a TagLib::String is posted below. It could be made more efficient with a stack buffer of a fixed size and iterative conversion but this works well enough.<div>

<br>
</div>I think you need to specify the encoding when you create the String / StringList:<br>
<br>
For instance:<br>
<br>
mp4tag->setTitle(String([@"ஜில்லுனு ஒரு காதல்" UTF8String], String::UTF8));<br>
<br>
constructors without a specific encoding Type assume Latin1.<br>
