Title-case presets are practical editorial approximations, not a substitute for checking the current full style manual for edge cases, names, or publication-specific rules.

Editorial title-case rules have edge cases, syllable counts are heuristic, Unicode style substitutions depend on font/app support, and normalized or visually similar Unicode text is not automatically safe or equivalent. Structural XML comparison should use the XML-aware engine rather than a raw line diff.
