About the Case Converter
The code-style cases (camelCase, PascalCase, snake_case, CONSTANT_CASE, kebab-case, dot.case) first split the input into words. Spaces, punctuation and existing separators are boundaries, and so are case changes, so userAccountId, user_account_id and User Account ID all give the same words. Runs of capitals are treated as acronyms: HTTPResponseCode splits into http response code.
With Remove accents in code cases, diacritics are stripped so identifiers stay ASCII: Danh sách đơn hàng becomes danhSachDonHang (including the Vietnamese đ). Title Case, Sentence case, lowercase, UPPERCASE, aLtErNaTiNg and iNVERSE keep the original characters and punctuation.
Title Case capitalises every word; it does not apply style-guide rules (AP, Chicago) that keep short words like “of” lowercase. Sentence case lowercases everything and capitalises the first letter of each sentence, so proper nouns need fixing by hand. With Convert each line separately, a list of names is converted line by line.
Digits stay attached to the preceding word: version2Api becomes version2_api.
