# extconv(1)

convert a TeX document in either Big 5+ or GBK encoding into \`preprocessed' form.

## NAME

extconv - convert a TeX document in either Big 5+ or GBK encoding into \`preprocessed' form.

## SYNOPSIS

**extconv** \< *infile* \> *outfile*

## DESCRIPTION

Big 5+ and GBK encodings use the characters {, }, and \\ which have special meanings in TeX documents.

After processing a LaTeX 2e document which contains such characters with **extconv** you need not care about these special characters.

This filter is part of the **CJK** macro package for LaTeX 2e.
