[LockedOnNone]

Code used.

const PDFMerge = require('pdf-merge');

const files = [
    `íñdigó çu+ - 中文平が Cómpênsã_1.pdf`,
    `íñdigó çu+ - 中文平が Cómpênsã_2.pdf`,
];

//Save as new file
PDFMerge(files, {output: `3.pdf`})
.then((buffer) => {

});

I'm not sure what part you consider the issue here: The unhandled exception - or that merging the files did not work due to unicode?

The unhandled exception would be because of missing .catch handler.

This lib makes no assumption of input being unicode or not, it simply passes it along to pdftk.

Yes, I forgot to indicate that the issue is the Unicode handling. I'll try and report this to pdftk, since it's a bug on their end. Thank you.
