    encoding.c: handle needmore error from rb_enc_precise_mbclen()
    
    rb_enc_ascget() erroneously reports success even if the given byte
    sequence is incomplete, for non-ASCII compatible encoding strings.
    
    rb_enc_precise_mbclen() may return a negative value on error, and thus
    rb_enc_ascget() must not store the return value in 'unsigned int';
    otherwise the subsequent MBCLEN_CHARFOUND_P() check won't catch the
    error.  [ruby-core:78646] [Bug #13034]
