\cs{lowercase} for changing +the case of text. However, these have a range of limitations: they only change +the case of explicit characters, do not account for the surrounding context, do +not support UTF-8 input with 8-bit engines, etc. To overcome this problem, +\LaTeX{} provides the commands \cs{MakeUppercase}, \cs{MakeLowercase} and +\cs{MakeTitlecase}: these offer significant enhancement over the \TeX{} +primitives. These commands are engine-robust (\cs{protected}), and so +can be used in moving arguments. + +Upper- and lower-casing are well-understood in general conversation. +Titlecasing here follows the definition given by the Unicode Consortium: the +first character of the input will be converted to (broadly) uppercase, and the +rest of the input to lowercase. The full range of Unicode UTF-8 input can be +supported, with the proviso that at present the characters set up with 8-bit +engines match those available in standard input encodings (|T1|, |T2|, |LGR|). +\begin{quotation} + \begin{tabular}{rl} + |\MakeUppercase{hello WORLD ßüé}| & \MakeUppercase{hello WORLD ßüé} \\ + |\MakeLowercase{hello WORLD ßüé}| & \MakeLowercase{hello WORLD ßüé} \\ + |\MakeTitlecase{hello WORLD ßüé}| & \MakeTitlecase{hello WORLD ßüé} \\ + \end{tabular} +\end{quotation} + +The input given to these commands is `expanded' before case changing is +applied.
