Unicode to LT-TM Tamil Font Conversion

Tamil is one of the most widely spoken classical languages, with a deep cultural and historical significance. With the digital revolution, communication in Tamil has shifted primarily to Unicode, the international standard for representing characters across systems and platforms. However, certain traditional and legacy fonts such as LT-TM Tamil Font are still actively used in specific industries, publishing systems, and older digital environments. This creates the practical need for Unicode to LT-TM Tamil Font Conversion.

What is Unicode?

Unicode is a standardized encoding system that provides unique code points for every character in every language. In the case of Tamil, Unicode ensures that text appears uniformly across devices, applications, and operating systems without the need for custom fonts. It is the backbone of modern digital communication, supporting web publishing, email, mobile devices, and international software platforms.

What is LT-TM Tamil Font?

LT-TM Tamil Font is a non-Unicode, legacy font that follows custom encoding. Similar to fonts like Bamini, TAB, or TAM, LT-TM maps Tamil characters onto English keystrokes. This means that unless the LT-TM font file is installed, the text will appear garbled. Despite Unicode’s rise, LT-TM continues to be used by certain publishing houses, government archives, and DTP professionals who are familiar with its typing method.

Why Convert Unicode to LT-TM Tamil Font?

Unicode is universal, but LT-TM persists in certain workflows. Conversion is essential for:

  • Publishing: Many newspapers, books, and magazines continue to use LT-TM.
  • Printing Presses: Printers may request LT-TM fonts for final layout.
  • Legacy Documents: Converting Unicode text for compatibility with old LT-TM archives.
  • User Familiarity: Professionals trained in LT-TM prefer working with it over Unicode.
  • Software Support: Some older Tamil publishing software supports LT-TM but not Unicode.

Challenges in Unicode to LT-TM Conversion

Conversion between Unicode and LT-TM is not direct because their encodings differ completely. Some challenges include:

  • Character Mapping: Each Unicode Tamil character must be matched with its LT-TM equivalent.
  • Complex Ligatures: Tamil has compound characters that require special handling in LT-TM.
  • Formatting Issues: Conversions may disrupt alignment, spacing, or text style.
  • Tool Accuracy: Not all converters produce accurate LT-TM output, sometimes causing errors in vowel signs and conjuncts.

Methods of Unicode to LT-TM Tamil Font Conversion

1. Manual Typing

A user can manually retype Unicode text into LT-TM using the LT-TM keyboard layout. This is reliable but extremely time-consuming, making it impractical for large texts.

2. Online Conversion Tools

Several websites offer free Unicode to LT-TM converters. Users can paste Unicode text into an input box and instantly generate LT-TM output.

3. Desktop Software

Specialized Tamil publishing software supports batch conversion of Unicode text into LT-TM. These tools are popular among DTP centers and printing-press operators.

4. Custom Scripts

Developers create custom scripts in Python, Java, or JavaScript to automate conversion. This is especially useful for large-scale document conversion projects or archival processing.
