I made a payment request using UTF-8 description here:
lntb1pdz7e9epp5qqqsyqcyq5rqwzqfqqqsyqcyq5rqwzqfqqqsyqcyq5rqwzqfqypqdpquwpc4curk03c9wlrswe78q4eyqc7d8d0e5l2jffz6amujxz82mtagde82dv8jku2jac79k0yxnjmr0l3f4y5x0jxt46vmcrc0ukzh7l99vdmkezsettfwr4gqnhs2ndx8wdqgfsp82rnvp

using this code: (I just separated encode from sign)

ln.sign(ln.encode({
  tags:[
    {
      tagName:'payment_hash',

data:'0001020304050607080900010203040506070809000102030405060708090102'
    },
    {
      tagName:'description',
      data:'????? 1?'
    }
  ]
}, false),
Buffer.from('e126f68f7eafcc8b74f54d269fe206be715000f94dac067d1c04a8ca3b2db734',
'hex')).paymentRequest
