SYV_ Symbol Values
Each glyph a recognizer can identify has an associated symbol value. It is
this value that is returned to the application by the recognizer.
The high-order and low-order words of a symbol value have the following
meanings:
High-order word
| Low-order word
| 0
| System symbols.
| -
| ANSI character code.
| -
| Gestures.
| -
| Shift character codes (kanji).
| -
| Shapes.
| -
| Unicode.
| -
| Virtual keys.
| - 0x7EFF
| Reserved for future use.
| 0x7F00-0x7FFF
| Recognizer-specific symbols.
| >=0x8000
| Character code for given code page. The low 15 bits of the high-order word
indicate the code page.
|
Recognizers for the European market should return symbol values using ANSI and
gesture symbol values (ANSI is the native character set for Windows in the
European market). For the Japanese market, recognizers can use Shift JIS Level 1
and gestures. When writing a recognizer, bear in mind that symbol values outside
these ranges cannot be interpreted by all Windows applications.
