The Sindhi Alphabet — Complete Unicode Reference
Sindhi uses one of the most distinctive implementations of the Perso-Arabic script. Unlike Urdu, which adapted Arabic script with a relatively small number of additions, Sindhi required a substantially expanded character set to represent its phonological inventory. The result is an alphabet of 52 letters — compared to Urdu's 38 or Arabic's 28 core consonants.
The International Organisation for Standardisation and the Unicode Consortium have assigned code points to all Sindhi-specific characters, primarily in the Arabic Supplement block (U+0750–U+077F) and the broader Arabic block (U+0600–U+06FF). This means text typed here works in any Unicode-aware environment without font substitution or rendering issues.
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+0644) 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. Windows, for instance, does not include Sindhi as a built-in keyboard language in most regional settings outside Pakistan. macOS has limited Sindhi support. Mobile operating systems vary — some Samsung devices include Sindhi, many iOS devices do not offer it as a first-party keyboard option.
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-language social media is substantial. Facebook has active Sindhi-language groups with millions of members. YouTube has Sindhi-language content from major Pakistani channels. Twitter (now X) has a significant Sindhi-speaking user base. All of these platforms accept Unicode text and display Sindhi correctly.
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.
