Unicode and Special Characters

The following steps illustrate Unicode specifications for a number of commonly used characters and create Output 22.2.6 and Output 22.2.7, which are charts of Unicode characters:

Output 22.2.6: Commonly Used Unicode and Special Characters

Output 22.2.7: Markers, Marker Names, Unicode Characters, Unicode Specifications

The Unicode Consortium http://unicode.org/ provides a list of character codes at
http://www.unicode.org/charts/charindex.html.

The following rules apply to Unicode and special character specifications in ODS graphics:

Each character can be specified by looking up its code and specifying it as a hexadecimal constant. Example: $\{$ unicode ’221e’x $\}$ .
Lower case Greek letters can be specified by using names instead of hexadecimal constants. Example: $\{$ unicode alpha $\}$ .
Upper case Greek letters can be specified by using names followed by _u instead of a hexadecimal constants. Example: $\{$ unicode alpha_u $\}$ .
Superscript and subscript have special abbreviations. Examples: $\{$ sup 2 $\}$ and $\{$ sub 2 $\}$ .
The sup and sub specifications must not appear escaped and in quotes in the GTL. They must appear outside of quotes.
Some characters overprint the character that comes before. Example: ’El nin’ $\{$ tilde $\}$ ’o’, which is equivalent to ’El nin’ $\{$ unicode ’0303’x $\}$ ’o’ creates 'El niño'.
Specifications inside quotes are escaped. Example: "(*ESC*) $\{$ unicode beta $\}$ ".
Specifications outside quotes are not escaped. Example: $\{$ unicode beta $\}$ .
