The Sindhi Alphabet — Unicode Reference
Sindhi uses a distinctive implementation of the Perso-Arabic script, with additional characters used to represent sounds specific to the language. This page focuses on the Unicode characters used for practical Sindhi typing and explains how those characters work in digital text.
The International Organisation for Standardisation and the Unicode Consortium have assigned code points to Sindhi-specific characters, primarily within the Arabic block (U+0600–U+06FF) and, for some characters, the Arabic Supplement block (U+0750–U+077F). This means text typed here uses standard Unicode characters. Display still depends on the receiving application, font coverage, and right-to-left shaping support.
Sindhi's Unique Letters
Several groups of letters give Sindhi its distinctive phonological character:
Implosive consonants: Sindhi distinguishes implosive from plain voiced stops. The letter ٻ (U+067B) represents the implosive /ɓ/, distinct from plain ب. Similarly ڄ (U+0684) marks the implosive /ɗ̠/. These sounds have no equivalent in Arabic or Urdu and mark Sindhi as phonologically closer to South Asian than West Asian languages.
Aspirated consonants: Sindhi marks aspiration with modified letter forms rather than a separate aspirating character. ٿ (aspirated retroflex stop), ڀ (aspirated bilabial stop), and ڃ (aspirated palatal affricate) all have dedicated Unicode code points.
Retroflex consonants: Like other South Asian languages, Sindhi distinguishes retroflex from dental stops. ڊ, ڌ, ڍ, and ڻ represent retroflex sounds with no Urdu counterpart.
Typing Sindhi on Different Platforms
The practical challenge of typing Sindhi varies significantly depending on what device and operating system you use. Operating-system support varies by platform, version, region, and keyboard provider. Microsoft currently lists Sindhi (Arabic) among supported Windows language resources, while mobile keyboard availability can vary between system keyboards and third-party keyboard apps.
This is why a browser-based keyboard is often the most reliable option. It does not depend on operating system support, driver installation, or administrative access to the machine you are using.
For users who do have a Sindhi keyboard installed on their system, the text area on this page accepts that input directly. You can use your physical keyboard in Sindhi mode and benefit from the character and word counters, and the one-click copy function.
Sindhi in Social Media
Sindhi is used across social media, video platforms, messaging services, and websites. Unicode makes it possible to copy and exchange Sindhi text between services, although final display depends on the receiving application and available fonts.
The common problem is that many users, lacking a convenient way to type correct Sindhi, substitute Urdu characters for Sindhi-specific ones or use romanised Sindhi instead. This degrades the consistency of Sindhi text online and makes it harder to search or archive. A reliable typing tool helps maintain spelling standards.
Sindhi Script History and the Unicode Question
Sindhi has been written in several scripts. The Khudabadi script, developed in the 16th century, was used by Sindhi traders and is still recognised by UNESCO as an endangered writing system. Devanagari Sindhi is used by the Sindhi-speaking communities in India. The Perso-Arabic form used here was standardised in the 19th century under British India and remains dominant among Sindhi speakers in Pakistan and the diaspora.
The Unicode Consortium addressed Sindhi's requirements by encoding its specific letters as part of the Arabic block expansion. This was not a simple matter — Sindhi letterforms required careful decisions about which characters could share code points with Arabic or Urdu equivalents and which genuinely needed independent encoding. The result is that modern Sindhi text can be stored, transmitted, and searched correctly without any proprietary font encoding.
Sindhi in Education
Sindhi is the medium of instruction in primary schools in Sindh province. Teachers preparing Sindhi-medium materials need reliable digital tools. When a teacher creates a test paper or worksheet on a computer without a Sindhi keyboard installed, this online keyboard provides an immediate solution. The output pastes cleanly into Word, LibreOffice, Google Docs, or any other word processor.
University students writing Sindhi-language theses or dissertations often encounter the same problem. Academic word processors do not always have Sindhi keyboard support, and the fallback of using Urdu characters for Sindhi sounds creates documents that are technically incorrect even if superficially readable.
