The Script Problem No One Talks About
Most e-signature platforms assume every signer writes in Latin script. That assumption holds for English, Spanish, and French. It breaks the moment your signer's name is Γιώργος, Сергей, 田中, or 김민준. A Latin cursive font applied to a Cyrillic or Kanji name doesn't look like a signature. It looks like a rendering error.
Automatic Script Detection, Zero Configuration
Firma.dev automatically detects the writing system in each signer's name and presents signature styles designed for that script, with no developer configuration required. Five script families are supported out of the box.
The Problem With Latin-Only Signature Styles
Wrong Font, Wrong Message
When a signer with a non-Latin name opens a signature modal and sees only cursive Latin fonts, two things happen. First, the signature doesn't look like their actual name. Second, it signals that the platform wasn't built with them in mind. For businesses where the signing experience is part of the product, both of those outcomes are problems.
These Are Real Markets, Not Edge Cases
This isn't a niche edge case. Russian enterprise users, Japanese HR onboarding flows, Korean financial services platforms, all of these are real markets where Latin-only signing looks wrong and erodes trust. The fix shouldn't require developer effort for every locale you support.
Automatic Detection With Manual Override
Automatic detection covers the majority of cases cleanly. For bilingual signers or names that include characters from multiple scripts, signers can switch families manually via a dropdown in the signature modal. The selection takes a single click and the available styles update immediately.
Zero Configuration for Developers
One Integration, Every Script
The integration code doesn't change. You set up signers the same way regardless of their writing system. Firma.dev handles script detection, font selection, and rendering behind the scenes.
Correct Rendering in Every Output, Automatically
Signatures render correctly in three places: the signing experience itself, the final signed PDF, and the completion certificate. All three are handled automatically. There's no post-processing step and no font embedding logic to manage on your side.
Global Signing, One API
For teams building global products, this means you can onboard signers in Japan, Russia, Greece, or Korea using the same API calls you use for everyone else. Localization at the signature level is handled without you having to think about it.
The signing interface around these signatures is available in 15 languages. See Multi-Language Signatures.
