Special symbols

When drawing text into the Picture window or into the TextGridEditor, you can use backslash sequences to display various kinds of special symbols. You can usually also type the characters themselves, if your computer has an input method for them.

European symbols

To get the symbol "â" (a-circumflex), you type "\a^", i.e., a sequence of backslash + a + circumflex. In this way, you can get a hundred non-ASCII symbols that are used in the alphabets of many European languages.
