Description

Environment

  • Tesseract Version: 3.04.01
  • Platform: both on Debian Linux Buster (testing) and Windows 7 64bit

Current Behavior:

In hOCR mode words bound by the / sign are regarded as one word.

Expected Behavior:

The / sign, the word before and after should be regarded as a word on its own each.

Suggested Fix:

Define the / sign as a word delimiter.

Research direction
The issue asks to treat '/' as a word delimiter in hOCR output. In Tesseract, word segmentation and delimiter handling is typically done in files like src/ccmain/paragraphs.cpp or src/ccutil/params.cpp. Look for existing delimiter definitions and modify the code to include '/' as a delimiter. Also check the hOCR output logic in src/output/hocr.cpp. Ensure the change is consistent with other delimiters.
