In convertUniCharToUTF8, utf8 got allocated memory via utf16_to_utf8(characters, length, utf8, new_length); But, It looks not released.

Comment on attachment 87280 [details] Patch Can't we use OwnGPtr?
Comment on attachment 87280 [details] Patch Great catch! I think we can use this opportunity to clean this code up a bit. We should probably make utf16_to_utf8 return a char* instead of taking a char*& (which is bad form, IMO). Then in the caller we should immediately place the return value in a GOwnPtr<gchar> and remove the calls to g_free. This will prevent any mistakes in the future as well.

Then in the caller we should immediately place the return value in a GOwnPtr<gchar> and remove the calls to g_free. This will prevent any mistakes in the future as well. I update patch as mentioned with refactoring utf16_to_utf8(because of fixing indentation and coding style). And also, can we remove 'from' variable in convertUniCharToUTF8? this value will be passed 0 always. Thanks.
