A comment on this thought. Internally, TeXShop is a Unicode editor. Thus if you
insert an umlaud or an accented o, you will get those characters. Indeed, if you
insert Arabic, you will get Arabic, written backward. If you insert Chinese, you get Chinese.
Line feeds and tabs don’t have characters to display. But TeXShop has a command called “Show Invisible
Characters” to make them visible.
Situations when the output display don’t show umlauts are usually related to
the coding used to read and write files. The common choices are
Western (ISO Latin 9)
Mac OS Roman
Originally, TeX only accepted ASCII input, and the default TeXShop encoding was Mac OS Roman. More recently it has been ISO Latin 9,
suitable for Western Europe; this is ISO Latin 1 with the addition of a Euro symbol.
The best choice is UTF-8, which preserves all Unicode, provided you can deal with the
issues of getting your TeX engine to accept this input.
