Greek OCR Guide — Extract Text from Ελληνικά PDFs & Images
Greek uses its own alphabet, and many Greek letters look deceptively like Latin letters. An OCR engine trained mainly on Latin text may output α as a, ρ as p, or ν as v, corrupting the text.
This guide explains how to extract accurate Greek text from scanned documents and images while keeping every letter in the correct alphabet.
Why Greek OCR Is Tricky
Greek letters often resemble Latin letters but encode very differently, and accents carry grammatical meaning.
- α, ε, ο, ρ, ν, χ look like a, e, o, p, v, x but are Greek Unicode characters.
- The tonos accent on vowels changes stress and meaning.
- Ancient and modern Greek use different accent systems.
- Mathematical texts mix Greek letters with Latin symbols and equations.
- Fonts without Greek support can corrupt extracted text on copy-paste.
