Visual FoxPro Requires Chilkat v11.7.0+

Rejoin Words Hyphenated at Line Ends

See more PDF Text Extraction Examples

Demonstrates the "dehyphenate" clean-up option (true by default). A word broken at the end of a line ("docu-" / "ment") is rejoined, while a hyphen that belongs to the word ("self-service") is kept. Set the option to false to keep the lines exactly as printed. Visual FoxPro

*  The paragraph breaks "document", "self-service", "underlying" and "re-issued" at line ends.
*  The default rejoins them.  "self-service" keeps its hyphen because the word appears with it,
*  unbroken, elsewhere on the page; "re-issued" appears nowhere else, so it becomes "reissued".

*  Sample output:

*  ---- default (dehyphenate: true) ----
*  Self-Service Kiosk Notes
*  
*  The new self-service kiosk in the lobby prints a visitor badge from the document number on the reservation. Staff should direct first-time visitors to the self-service kiosk rather than the desk, and should keep the paper tray topped up. The underlying software restarts itself overnight; a badge that fails to print is reissued at the desk on request.
