How these characters were chosen
Japanese has no letters for foreign names, so a name is first written in katakana — ルビー — which records how it sounds. Kanji are then chosen whose readings match those sounds. Because many characters share the same reading, there is never a single correct spelling; there are only choices, and each one changes what the name says.
留美 is built from 留 (remain), 美 (beauty). Every character here comes from a hand-checked dictionary, and combinations that happen to spell an ordinary Japanese word are rejected before you ever see them.
