Comparison settings can ignore letter case, whitespace, leading or trailing spaces, and blank lines. Supported encodings include ANSI, ASCII, UTF-8, UTF-8 with BOM, and UTF-16. Optional Apache Tika support extracts readable text from PDF, DOCX, XLSX, and PPTX files for comparison. Version 2.2 is dated September 23, 2026.
