LaTeX Unicode Encoder

Convert Unicode characters to LaTeX command syntax for use in LaTeX documents.

Usage

npx tsx scripts/encode.ts [options] <text-or-file>

Options

• --file - Read input from file instead of command line argument
• --output <file> - Write output to file
• --format <type> - Output format: braced (default) or compact

Examples

Encode text with accents

npx tsx scripts/encode.ts "café naïve"
# Output: caf\'{e} na\"{i}ve

Encode from file

npx tsx scripts/encode.ts --file input.txt --output output.tex

Encode for BibTeX

npx tsx scripts/encode.ts --format braced "Müller"
# Output: M\"{u}ller

Supported Characters

• Accented characters: é, è, ê, ë, ñ, ü, etc.
• Ligatures: æ, œ, ß
• Special characters: &, %, $, #, _
• Greek letters: α, β, γ, δ, etc.
• Dashes: – (en-dash), — (em-dash)

Technical Details

The encoder converts Unicode characters to LaTeX commands using a comprehensive mapping table:

• Accented vowels: é → \'{e}, ü → \"{u}
• Special characters: & → \&, % → \%
• Ligatures: æ → \ae, ß → \ss

Regular spaces are NOT escaped. Only special LaTeX characters and Unicode characters without ASCII equivalents are encoded.
