Title Case follows French usage: common function words (de, la, le, et, à…) keep their lowercase, except at the start of the text. Use "Capitalize Each Word" if you want everything capitalized.
These technical formats strip accents and punctuation to produce valid identifiers (variables, keys). The original text is not modified until you copy the result.
