é is converted to é

[godspeedelbow]

é is converted to é (String), if you open the binary plist file in Xcode (or on an iOS device).

When I change the Type to Data it is listed as <c383c2a9>.

Logging entry and utf8 values in bplistCreator.js on line 226, gives: entry { type: 'string', value: 'é', id: 2 } utf8 <Buffer c3 a9>

According to http://utf8-chartable.de/ the UTF-8 code for é is c3 a9, which make up the first and last two characters of <c383c2a9>. The code in between 83 c2 makes two characters:
c383: Ã and c2a9: ©.

Input	String	Data
é	é	< c3 83 c2 a9 >
ê	ê	< c3 83 c2 aa >
ë	ë	< c3 83 c2 ab >
è	è	< c3 83 c2 a8 >

It looks like somewhere UTF-8 text is being decoded as ISO-8859-1 or a similar text encoding.

There doesn't seem to be an issue here:

const fs = require('fs');
const bplist = require('bplist-creator');
const plist =  bplist({test: "é"});
fs.writeFileSync('test.plist', plist);

$ plutil -convert xml1 test.plist
$ cat test.plist
<?xml version="1.0" encoding="UTF-8"?>
