maybe It would be nice to be able to specify what encoding to use instead. Changing the default encoding will be a breaking change. What about people that don't want/can't use utf8?

Sorry for the late response on this.

It feels like this is a breaking change? In that case I don't see how we could get it into the 1.x release, but maybe we can do the same change in the 2.x branch? (#399)

yes, because currently, people are using the Buffer.from(filename, 'latin1').toString('utf8'); trick.
If we parse an utf8 string as latin1 it will spit out garbage.

That's why I suggested only adding an option to change the encoding as a config option but leaving the default one as is to not break existing setups.

but maybe we can do the same change in the 2.x branch?

sounds good as well

@LinusU I created a different PR that doesn't break backward compatibility - it extends the multer's API with a default defParamCharset: 'latin1' value
Also, improved the translations
