Standard transliteration. The middle dot · (
隔音号 'syllable separator') is the convention for Western names with a given-name/surname split when the parts are short enough to risk being read as a Chinese name.
李 (lǐ) covers 'Lee';
卡特 (kǎtè) covers 'Carter' — the same characters used to render U.S. President Jimmy Carter (
吉米·
卡特).
