php codegen when using double byte chatecters in object string

[neimanpinchas]

I am using this haxe code

function main() {
    Sys.println("אבגדהו");
    var list={
        "אבגדהו":"abcd",
        "אבדהו":"abcd",
    }
    trace(list);
}

In the first print, the Hebrew characters are copied directly to the resulting php file.

However for the object keys, they are trying to get escaped, but the algorithm is not good.
א
in utf8 is D7 90

this is 215 144 in decimal

PHP would interpret backslash escape as octal, but the Haxe generator inserts the decimal values instead.

The result is that the characters render as gibberish.

It would need any of the follwing

1. leave the original text (php supports inline utf8)
2. use octal values
3. escape with haxedecimal escaping

I tried to navigate the php7 gen file, but was unsuccesfull in finding the cause.

In control charecters less then ASCII 32, the generator is using haxedecimal escaping such as \x0A which is good.

generates the follwing php

<?php
/**
 * Generated by Haxe 4.3.4
 */

namespace _TestPhp;

use \php\_Boot\HxAnon;
use \php\Boot;
use \haxe\Log;

final class TestPhp_Fields_ {
	/**
	 * @return void
	 */
	public static function main () {
		#TestPhp.hx:2: characters 5-26
		echo("אבגדהו" . \PHP_EOL);
		#TestPhp.hx:3: lines 3-6
		$list = new HxAnon([
			"\215\144\215\145\215\146\215\147\215\148\215\149" => "abcd",
			"\215\144\215\145\215\147\215\148\215\149" => "abcd",
		]);
		#TestPhp.hx:7: characters 5-10
		(Log::$trace)($list, new HxAnon([
			"fileName" => "TestPhp.hx",
			"lineNumber" => 7,
			"className" => "_TestPhp.TestPhp_Fields_",
			"methodName" => "main",
		]));
	}
}

Boot::registerClass(TestPhp_Fields_::class, '_TestPhp.TestPhp_Fields_');
