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.
