System Information & Engine Details

1. What the Tool Does & Privacy Guarantee

Akuru Tools provides instant bidirectional conversion between standard Sinhala Unicode and FM Abhaya legacy font encoding.

Privacy Assurance: 100% of conversion logic executes directly inside your browser using vanilla JavaScript. Your text is never uploaded to any server, database, or third-party API. No tracking, accounts, or analytics scripts are used.

2. Conversion Engine Architecture

Text transformation is executed line-by-line to guarantee responsive UI behavior even on large text passages (hundreds of kilobytes):

  • FM Abhaya Legacy ↔ Unicode: Legacy-to-Unicode applies contextual rule transformations in a single regex pass, followed by greedy longest-match glyph substitution. Unicode-to-FM applies prefix vowel sign transposition (typing ෙ, ේ, ෛ, ො, ෝ, ෞ before consonants), handles rakaransha/yansaya suffix positioning, and provides yansaya conjunct fallback.

3. Testing & Documented Limits

  • Automated Verification: Validated against automated test suites, including comprehensive real-world passages and isolated word test vectors. The engine executes automated self-tests upon startup.
  • Multiple Valid Encodings: Certain Sinhala characters have multiple equivalent legacy keystrokes depending on specific typesetter layouts; output may differ from alternative tools while remaining typographically accurate.
  • Repaya Notice: Repaya (ර් + consonant) forms are not independently standardized across all legacy tables.
  • Beta Designation: Unicode → Legacy font conversion is strictly designated as Beta. Always proofread converted desktop publishing materials before final printing.

4. Engine & Font Information

  • FM Abhaya Font: Originally designed by Font Master (Fernando & Mudannayake / Pushpananda Ekanayaka). The FM Abhaya font file is proprietary and is neither hosted, distributed, nor bundled by Akuru Tools. If installed on your system, the browser natively applies it.
  • Akuru Tools Conversion Engine: Bespoke, custom bidirectional mapping engine created and maintained by Akuru Tools, audited and verified across 760+ Sinhala phoneme/vowel combinations and natural Sinhala text passages.
