2. COPY COMMAND (Run as Administrator):
Option A - File Explorer:
- Open: {temp_dir}
- Select all .traineddata files
- Copy and paste to: {tessdata_dir}
Option B - Command Prompt (as Admin):
copy "{temp_dir}\\*.traineddata" "{tessdata_dir}\\"

1. FIND TESSERACT TESSDATA DIRECTORY:
Common locations:
- C:\\Program Files\\Tesseract-OCR\\tessdata\\
- C:\\Program Files (x86)\\Tesseract-OCR\\tessdata\\
2. COPY FILES:
Copy all .traineddata files from:
{temp_dir}
To your Tesseract tessdata directory
"""

3. VERIFY INSTALLATION:
tesseract --list-langs
Should show:
ā
eng (English)
ā
ind (Indonesian)
ā
msa (Malay)
ā
osd (Orientation and script detection)
4. TEST ENG+IND COMBINATION:
tesseract input.pdf output.txt -l eng+ind
5. USAGE IN MCP TOOLS:
- process_pdf_smart(pdf_path, language='eng+ind')
- perform_ocr(file_path, language='eng+ind')
- batch_process_pdfs(directory, language='eng+ind')
OPTIMAL LANGUAGE SETTINGS:
- Mixed documents: lang='eng+ind' (RECOMMENDED)
- Fallback: lang='eng' (English only)
AFTER INSTALLATION:
- Test with: python test_indonesian_support.py
- Check tools: python validate_tools.py
