In this chapter we will tackle matters related to input encoding, typesetting diacritics and special characters. First we show the arrow symbols which are available without an extra usepackage. Example: Now inputting ŷ will effectively print ŷ. Some languages usually need a dedicated input system to ease document writing. And a visible space ␣ can be created with \textvisiblespace. This is very useful if one needs to use some text accents in a label, since no backslash will be accepted otherwise. Supports the complete Unicode specification. \newcommand{\vect}[1]{\boldsymbol{#1}} % Uncomment for BOLD vectors. Use the textcomp package instead, which provides a \textdegree command.
