Unicode-Preeti Text Converter

Overview

This is a web-based utility for converting text between Unicode and Preeti encoding formats, specifically designed for Nepali language text processing. The application allows users to seamlessly convert text between two different character encodings, which is particularly useful for working with legacy Devanagari text documents.

Features

• Convert text from legacy Preeti encoding to Unicode
• Convert text from Unicode back to Preeti encoding
• Handles complex Devanagari character transformations
• Supports Nepali numerals and special characters
• Preserves text formatting and diacritical marks

How It Works

The converter uses two main functions:

1. convert_to_unicode(): Transforms text from Preeti encoding to Unicode
2. convert_to_Preeti(): Converts Unicode text back to Preeti encoding

Both functions use extensive character mapping arrays to handle the intricate transformations between encoding systems.
