The following English messages have been inserted to localized files.
{ "plugin_converter.write_permission", "Need to have the write permission in the current work directory"},
{ "plugin_converter.overwrite", "The temporary file .tmpSource_stdin already exists. Please delete or rename it."},
" -source -: read converting file from the standard input" + newline +
" -dest -: write converted file to the standard output" + newline +

(these messages have been added after l10n team started hopper-beta translation).
