Senthamizh to Unicode Tamil Font Conversion

Tamil, one of the world’s oldest classical languages, has a profound literary and cultural heritage. Over the years, Tamil text has been typed and published using various non-Unicode fonts, including Senthamizh. While Senthamizh font has been widely used in newspapers, books, official documents, and educational materials, the rise of Unicode as a global standard has made converting Senthamizh text to Unicode critical for digital compatibility, accessibility, and professional publishing.

Understanding Senthamizh Font

Senthamizh 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, Senthamizh uses a custom keyboard layout. For example, typing "k" may display "க" depending on the Senthamizh mapping. Without the font installed, the text appears as random English letters or symbols, making it unreadable on modern systems.

Senthamizh font became popular for its ease of typing and compatibility with desktop publishing software. Many printed newspapers, books, and government documents were created using this font before Unicode adoption.

Why Convert Senthamizh to Unicode?

Converting Senthamizh 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 Senthamizh font.
• Web and Mobile Accessibility: Modern websites, 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, magazines, books, and official documents require Unicode for standardization.
• Future-Proofing: Unicode ensures long-term readability and compatibility with new technologies.

Challenges in Senthamizh to Unicode Conversion

Converting Senthamizh font text to Unicode presents several challenges:

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