/*
 * Simplistic program to correct Big5 inside strings.  When a trail byte is a
 * backslash it needs to be doubled.
 * Public domain.

/*
 * 06.11.23, added by Restorer:
 * For more details, see:

 * https://github.com/vim/vim/pull/12153
 * (read all comments)
 *
 * I checked the workability on the list of backslash characters
 * specified in zh_TW.UTF-8.po. It works.
 * But it is better to have someone native speaker check it.
