+/** Cross-platform function to open files with a UTF-8 encoded name.

+ This function is especially useful under the MSWindows platform where the 
+ standard fopen() function fails with UTF-8 encoded non-ASCII filenames.
+ \param f  the UTF-8 encoded filename
+ \param mode  same as the second argument of the standard fopen() function
+ \return  a FILE pointer upon successful completion, or NULL in case of error.
