Language support for OCR tool

[simonw]

A few people mentioned that it doesn't work for their language. Tesseract.js has that support built in, but I need to expose it as a select box.

Tesseract.languages has this:

It would be nice to have non-acronym names for them too.

Those are mostly ISO three letter codes, but not all.

I found uzb_cyrl defined on a table on https://www.imageen.com/files/IEVision_OCR/ as "Uzbek - Cyrillic".

[simonw]

I selected that table as temp0 and ran this on that page:

Object.fromEntries(Array.from(temp0.querySelectorAll('tr')).slice(1).map(tr => {
  return [tr.querySelectorAll('td')[0].innerText, tr.querySelectorAll('td')[1].innerText]
}))

Would be neat if this was bookmarkable, so you could bookmark a specific language. May as well make the back/forward/URL bar work too.
