Obsolete since JSAPI 35
This feature is obsolete. Although it may still work in some browsers, its use is discouraged since it could be removed at any time. Try to avoid using it.
jschar, a typedef for the standard C++ type char16_t, will be removed in JSAPI 38. Functions that use
jschar will use
char16_t directly. Embedder code should use
char16_t, too. (See bug 1063962.)
