multer-utf8

multer-utf8 is a solution for latin1 charset issue.

busboy reads files with latin1 charset by default, which causes some problems with utf8 encoded files.

I fixed it by changing this part of code.

try {
  busboy = Busboy({ headers: req.headers, limits: limits, ßpreservePath: preservePath, defParamCharset: charset })
} catch (err) {
  return next(err)
}

Options

Key	Description
dest or storage	Where to store the files
fileFilter	Function to control which files are accepted
limits	Limits of the uploaded data
preservePath	Keep the full path of files instead of just the base name
charset	charset of files. for example latin1, utf8

Support latin1

/**
* mutler for utf8 
* default charset is `utf8`
*/ 

const multerWithUTF8 = multer({
  ...mutlerOptions
})

// multer for latin1
const multer = multer({
  ...multerOptions
  charset: 'latin1'
});
