To expand on the sibling comments: This encoding (called Punycode) works by combining the character to encode (é) and the position the character should be in (the 7th position out of a possible 7) into a single number. é is 233, there are 7 possible positions, and it is in position 6 (0-indexed) so that single number is 233 * 7 + 6 = 1637. This is then encoded via a fairly complex variable-length encoding scheme into the letters "fsa".
