filenames with Unicode characters are corrupt

Similar to another issue, filenames with Unicode characters are unusable: 7-zip can neither read nor extract them.

For example:

Tal/A L'infini/Le Passé.txt -> Tal/A L'infini/Le Passé.tx

Snøfall.txt -> Sn├╕fall.tx

I just tested this code, little modified example code and for my surprise

1. if Bit 11 is set but mode is not written - GUI tools understand filenames, but command line tools doesn’t. .
2. if Bit 11 is not set and mode is Unix - command line tools understand file names, but GUI tools doesn’t.
3. if Bit 11 is set and mode is Unix - Both GUI and command line command line tools understand file names .

#!/usr/bin/env node

const AdmZip = require('adm-zip');

const zip = new AdmZip();

// add file directly
const content = "inner content of the file";
//zip.addFile("äää.txt", Buffer.from(content), "entry comment goes here");
zip.addFile("你好.txt", Buffer.from(content), "entry comment goes here");

zip.getEntries().forEach(entry => {
    entry.header.made = 0x314;
    entry.header.flags |= 0x800;   // Set bit 11 - APP Note 4.4.4 Language encoding flag (EFS)
});

const willSendthis = zip.toBuffer();

zip.writeZip('./test-utf8.zip');

for GUI tools I used only Gnome Archive Manager. I also used google drive for testing but it detected correct names with every try.

I have same problem. Have you solved this?
