Chārī

While チャーリー is used for people, Japanese uses a different set of loanwords for 'Charles' depending on whether the person is French シャルル or English チャールズ.
Because Japanese phonology lacks a standalone 'r' sound, チャーリー uses the Japanese 'r' which is a flap sound, making it sound like a cross between an 'r', 'l' and 'd' to English ears.
In Japanese pop culture, the name チャーリー is frequently used for characters meant to seem 'Western' or 'exotic' even if the character is not actually from an English-speaking country.
