• Substitute String Character List (array of UI)—the characters

which make up the substitute string. Each character is

represented as a UI value. If the font is a bound font, then the

values are accessed by their character codes values; if the font

is unbound, then the Unicode index numbers (see

Appendix D) are used.

The Typeface String Segment will be invalid if the Data Segment Size

declared in the Data Segment Size field is larger or smaller than

required for substitute string length, or if the Data Segment Size is an

odd number of bytes. If the segment is invalid, the font download will

be ignored.

Typeface String Segments can be downloaded with any Font

Format 15 or Font Format 16 font, regardless of font type.

The following tables are examples of Typeface String Segments for

two downloaded fonts. The first is for MS Mincho, and has the

embedded font name flag set to true. The second is for MS Gothic,

and has the embedded font name flag set to false.
