Japanese Transliteration in Node.js and Kakasi - node.js

Question

I have written a little wrapper for Kakasi
that is like the following:
Kakasi.prototype.transliterate = function (data) {
var self = this;
return new Promise(function (resolve, reject) {
var args;
args = [
'-i',
'euc',
'-Ha',
'-Ka',
'-Ja',
'-Ea',
'-ka',
'-s',
'-iutf8',
'-outf8'
];
var kakasi = spawn(self._options.bin, args, {});
console.log( "echo \""+data+"\" | " + kakasi.spawnargs.join(' ') )
args = [
data
];
var echo = spawn('echo', args, {});
echo.stdout.pipe( kakasi.stdin );
var res='';
kakasi.stdout.on('data', function(_data) {
var data=new Buffer(_data,'utf-8').toString();
res+=data;
});
kakasi.stdout.on('end', function(_) {
return resolve(res);
});
kakasi.on('error', function(error) {
return reject(error);
});
if (self._options.debug) kakasi.stdout.pipe(process.stdout);
});
}//transliterate
This code basically does the following command
echo "退屈であくびばっかしていた毎日" | kakasi -i euc -Ha -Ka -Ja -Ea -ka -s -iutf8 -outf8
that outputs taikutsu deakubibakkashiteita mainichi
Problem is that the javascript is missing some output infact:
$ node transliterate.js
echo "退屈であくびばっかしていた毎日" | kakasi -i euc -Ha -Ka -Ja -Ea -ka -s -iutf8 -outf8
----------
deakubibakkashiteita
The input parameters are the same, but for some reason (encoding?) the child output to stdout is different.
The kakasi.js code is available here.

I think your dictionary loader causes this problem. You should flip the dictionaries as follows.
process.env.KANWADICTPATH = resolve('./data/kanwadict');
process.env.ITAIJIDICTPATH = resolve('./data/itaijidict');
instead of
process.env.KANWADICTPATH = resolve('./data/itaijidict');
process.env.ITAIJIDICTPATH = resolve('./data/kanwadict');
