Arabisch- und RTL-CAPTCHA-Handhabung mit CaptchaAI

Arabische, persische und hebräische Websites präsentieren CAPTCHAs mit Rechts-nach-Links-Skripten (RTL), die Standard-OCR und Textinjektion in Frage stellen. Arabische Zeichen werden je nach Position unterschiedlich verbunden – Anfangs-, Mittel-, End- oder Einzelform –, was die Erkennung von Bild-CAPTCHAS erschwert. In Kombination mit RTL-Seitenlayouts, die sich auf die Elementpositionierung auswirken, erfordern diese Websites eine besondere Handhabung.
