Supported Scripts
Five writing systems, checked font by font.
Latin script 28 languages
Full accented-character sets, not just plain A to Z, verified for each language's own diacritics.
Cyrillic script 6 languages
Standard Slavic Cyrillic is fully covered. Central Asian variants with extra letters, like Kazakh, Kyrgyz, and Tajik, aren't covered yet. See the unsupported list below.
Greek script 1 language
Modern Greek, including accented (tonos) vowel forms.
Arabic script 6 languages
Full contextual letter shaping and correct right-to-left rendering, including lines that mix Arabic and Latin text in the same sentence.
Japanese 1 language
Covers the 2,136 official Joyo Kanji, full Hiragana, full Katakana, and Japanese punctuation. Kanji outside that set, mostly proper nouns and specialized or classical text, gets an on-screen warning instead of being dropped silently. Chinese and Korean aren't supported yet.
Not currently supported
Editing existing text in these languages may still work depending on the file, but typing new text isn't supported yet. The editor flags unsupported characters with an on-screen warning instead of dropping them silently.
Scanned PDFs use a different language list
Everything above covers typing or editing text in the PDF editor. Reading text out of a scanned document, OCR, is a separate step with its own language list.
The in-editor "Make text editable" shortcut currently reads English only. For other languages, use the dedicated PDF OCR tool instead, which lets you choose the document's language before scanning:
| OCR tool | Where to find it | Languages |
|---|---|---|
| "Make text editable" (in-editor shortcut) | PDF Editor → More tools menu | English only |
| PDF OCR (dedicated tool) | Its own page, separate from the editor | English, Spanish, French, German, Portuguese, Italian, Dutch, Arabic, Hindi, Russian, Chinese (Simplified), Japanese |
OCR only affects whether existing scanned text becomes selectable. It doesn't change which languages you can type new text in afterward. That's still governed by the five scripts above.
How This Actually Works
When you type or edit text in a PDF, the editor draws that text using one of a small set of bundled fonts rather than whatever font happens to be installed on your computer. That's what makes it consistent across every device, but it also means language support comes down to which letters those specific fonts actually contain. A language only makes the list below if its full character set, including accented and extra letters, was checked directly against the font files, not just assumed from "the font supports Latin script" style claims.
What Happens If You Type an Unsupported Language?
You won't get silently broken or missing text. Before drawing anything, the editor checks your text against the available fonts, and if it finds characters that aren't covered, it shows an on-screen warning that names the specific characters involved. You'll know immediately if something won't render correctly, instead of finding out after you've already exported and sent the file.
Languages Not Yet Supported for Typing
Vietnamese, Hebrew, Chinese, Korean, Hindi, Thai, Bengali, and the Cyrillic-script forms of Kazakh, Kyrgyz, and Tajik. If your language is in this list, typing new text with the editor's tools isn't reliable yet.
One important distinction: this limit is about typing new text. If you open a PDF that already contains Chinese, Hindi, or any other language, you can read it completely normally, since that's just your browser displaying content that's already in the file. The font limitation only applies when the editor itself has to draw brand-new characters into the page.
Language support questions
Does Raha PDF Editor support my language?
It supports 42 languages across five writing systems: Latin, Cyrillic, Greek, Arabic, and Japanese. This covers most of Europe, Latin America, Central Asia, and the Arabic-script languages (Arabic, Persian, Urdu, Pashto, Kurdish Sorani, and Sindhi). Chinese, Korean, Hindi, Thai, Bengali, Hebrew, and Vietnamese are not yet supported for typing new text.
Does it support Arabic and other right-to-left languages?
Yes. Arabic is fully supported with correct right-to-left rendering and proper contextual letter shaping, and it handles lines that mix Arabic and Latin text correctly. Persian, Urdu, Pashto, Kurdish Sorani, and Sindhi are also supported, since they share the Arabic script and their extra letters are included in the bundled font.
Does it support Japanese?
Yes. It covers the 2,136 official Joyo Kanji (the government-defined common-use set), plus full Hiragana, Katakana, and Japanese punctuation. Rare kanji outside the Joyo set, mostly proper nouns and specialized terminology, aren't covered yet and are flagged with an on-screen warning. Chinese and Korean are not yet supported.
What happens if I type a language it doesn't support?
The editor checks your text against the available fonts before drawing it. If any characters aren't covered, it shows an on-screen warning naming the specific characters, rather than silently dropping or corrupting them.
Can I still open and read a PDF written in an unsupported language?
Yes. The language limits described here apply to typing or editing new text with the editor's tools. Opening and reading a PDF that already contains text in any language works normally, since that's just the browser displaying the file's existing content.
Is OCR available in other languages too?
OCR has its own, separate language list. The one-click Make text editable shortcut inside the PDF editor currently reads English only. For other languages, use the dedicated PDF OCR tool, which supports English, Spanish, French, German, Portuguese, Italian, Dutch, Arabic, Hindi, Russian, Chinese (Simplified), and Japanese.
