Property Value

The character used as a symbol for the missing characters in the final output document.
Remarks

The missing symbol is a special character that replaces another character that was recognized by the engine but could not be represented in the final output document, since the character does not exist in the current code page.

During the conversion to the final output document the IOcrDocument.Save or IOcrDocument.SaveXml methods will try to find a replacement character with a similar shape for one not supported by the current code page. Only if this attempt was not successful the missing symbol will be sent into the final output document.

The default missing symbol is "^" (the circumflex character)

For more information on recognition and rejected and missing symbols, refer to IOcrPage.Recognize.

Note: This property is not supported in the LEADTOOLS OCR Advantage Engine

Example
For an example, refer to IOcrDocumentManager.
