: -use <fs/unicode.h> for utf16->utf8 conversion instead of a private
:  implementation

  Please note that fs/unicode.h does not handle UTF-16 surrogates
correctly.  What's worth, the API does not allow this to be fixed.

  (Unicode defines more characters than fit in a 16 bit int.  In
UTF-16, a character with a code above 0xffff is represented as two
surrogate values.  In UTF-8, it is encoded as a 5 byte sequence.
Encoding/decoding one 16 bit value at a time does not allow for this
conversion to be done correctly.)
