Senthamil to Unicode Tamil Font Conversion

Tamil, one of the world's oldest classical languages, has a rich literary and cultural heritage. Over the years, Tamil content has been typed and published using various non-Unicode fonts, including Senthamil. Senthamil font was widely used in newspapers, books, official documents, and educational materials. With the adoption of Unicode as a global standard, converting Senthamil text to Unicode has become essential for digital compatibility, accessibility, and modern publishing practices.

Understanding Senthamil Font

Senthamil is a non-Unicode Tamil font that maps Tamil letters to English keyboard keys. Unlike Unicode, which assigns a unique code to each Tamil character, Senthamil uses a custom keyboard layout. For example, typing "k" may display "க" depending on the Senthamil mapping. Without the font installed, text appears as unreadable English characters or symbols, which limits its usability in modern digital systems.

The font became popular because it allowed fast typing and was compatible with desktop publishing software. Many printed newspapers, books, and government documents were created using Senthamil before Unicode became standard.

Why Convert Senthamil to Unicode?

Converting Senthamil to Unicode is essential for several reasons:

• Cross-Platform Compatibility: Unicode ensures Tamil text can be read on all modern devices and operating systems without installing Senthamil font.
• Web and Mobile Accessibility: Websites, mobile apps, and social media platforms primarily support Unicode Tamil.
• Editing and Archiving: Unicode text is easier to store, search, edit, and manage digitally.
• Professional Publishing: Newspapers, books, magazines, and official documents require Unicode for standardization.
• Future-Proofing: Unicode ensures long-term readability and compatibility with evolving technologies.

Challenges in Senthamil to Unicode Conversion

Converting Senthamil text to Unicode comes with several challenges:

• Encoding Differences: Senthamil maps Tamil letters to English keys, while Unicode uses a universal encoding standard.
• Compound Characters: Ligatures like க்ஷ, ஸ்ரீ, and றை require precise mapping to Unicode.
• Vowel Signs: Correct placement of vowel markers (உயிர்மெய்கள்) is crucial to maintain accurate spelling.
• Formatting Issues: Bold, italics, and spacing may not transfer properly during conversion.
• Font Dependency: Senthamil text is unreadable without the font, requiring conversion for modern use.
