The release notes for version 4.0.0 claim that initialization parameters can now be set, which resolved #613. This was definitely implemented in a development branch, however appears to either have never been fully implemented in the master, or was implemented but somehow later reverted. Regardless, this feature does not work in the current version of Tesseract.js. This should be fixed.
Additionally, this feature was never documented in the api.md file, so that should be done as well.
