Penanganan CAPTCHA Arab dan RTL dengan CaptchaAI

Situs web berbahasa Arab, Farsi, dan Ibrani menyajikan CAPTCHA dengan skrip kanan-ke-kiri (RTL) yang menantang standar OCR dan injeksi teks. Karakter Arab terhubung secara berbeda berdasarkan posisi — bentuk awal, medial, akhir, atau terisolasi — membuat pengenalan gambar CAPTCHA menjadi lebih sulit. Dikombinasikan dengan tata letak halaman RTL yang memengaruhi posisi elemen, situs-situs ini memerlukan penanganan khusus.

Skrip RTL yang Didukung

Pemecahan Masalah

Pertanyaan Umum

Apakah CaptchaAI menangani skrip Arab yang terhubung?

Ya. Karakter Arab terhubung ketika berdekatan — huruf yang sama terlihat berbeda tergantung pada posisinya dalam sebuah kata. Pemecah Image/OCR CaptchaAI mengenali aksara Arab yang terhubung termasuk bentuk huruf awal, tengah, akhir, dan terisolasi.

Bagaimana cara menangani CAPTCHA Farsi vs. CAPTCHA Arab?

Keduanya menggunakan aksara Arab tetapi dengan karakter tambahan (seperti Ù¾, Ú†, Ú˜, Ú¯ dalam bahasa Farsi). Gunakan language=2 untuk keduanya. CaptchaAI mengenali kumpulan karakter yang diperluas secara otomatis.

Apakah tata letak halaman RTL memengaruhi deteksi CAPTCHA?

Tata letak RTL mencerminkan halaman – formulir dan CAPTCHA mungkin muncul di sisi yang berlawanan dibandingkan dengan halaman LTR. Gunakan pemilih atau ID CSS untuk menemukan elemen CAPTCHA daripada mengandalkan posisi visual.
