ScriptCodeRun

To return the result of a multiple encoding conversion, the function ConvertFromUnicodeToScriptCodeRun (page 155) uses a script code run structure.

The script code run structure uses an extended script code with values in the range 0-254, which are the text encoding base equivalents to Mac OS encodings. Values 0-32 correspond directly to traditional script codes. This allows a script code run to distinguish Icelandic, Turkish, Symbol, Zapf Dingbats, and so on.

A script code run structure is defined by the ScriptCodeRun data type.

struct ScriptCodeRun {
   ByteOffset     offset;  
   ScriptCode     script;     
};
typedef struct ScriptCodeRun ScriptCodeRun;

Field Description

offset

The beginning character position of a text run and its script code in the converted text.

script

The script code for the text that begins at the position specified.
