Negative prices missing minus

[jtojnar]

On Wedos, the negative prices are listed as positive.

Simple repro:

<?php
$formatter = new \NumberFormatter('en', \NumberFormatter::CURRENCY);
var_dump($formatter->format('-1'));

On Wedos (PHP 7.3), it returns string(8) "(¤1.00)", whereas locally, string(7) "-¤1.00", as expected (both PHP 8.0 and 7.3).

Weirdly, for Czech, it shows the minus sign:

<?php
foreach (['cs', 'en'] as $lang) {
	foreach (['1', '-1'] as $val) {
		echo $lang . ' ' . $val . ' ';
		$formatter = new \NumberFormatter($lang, \NumberFormatter::CURRENCY);
		var_dump($formatter->format($val));
	}
}

Locally,

cs 1 string(9) "1,00 XXX"
cs -1 string(10) "-1,00 XXX"
en 1 string(6) "¤1.00"
en -1 string(7) "-¤1.00"

On Wedos:

cs 1 string(8) "1,00 ¤"
cs -1 string(9) "-1,00 ¤"
en 1 string(6) "¤1.00"
en -1 string(8) "(¤1.00)"

The library actually uses formatCurrency internally so the symbol is already substituted.

<?php
foreach (['cs', 'en'] as $lang) {
	foreach (['1', '-1'] as $val) {
		echo $lang . ' ' . $val . ' ';
		$formatter = new \NumberFormatter($lang, \NumberFormatter::CURRENCY);
		var_dump($formatter->format($val));
	}
}

Locally,

cs 1 string(9) "1,00 Kč"
cs -1 string(10) "-1,00 Kč"
en 1 string(9) "CZK 1.00"
en -1 string(10) "-CZK 1.00"

On Wedos:

cs 1 string(9) "1,00 Kč"
cs -1 string(10) "-1,00 Kč"
en 1 string(7) "Kč1.00"
en -1 string(9) "(Kč1.00)"

Likely, this is due to outdated ICU:

Locally:

Internationalization support	enabled
ICU version	64.2
ICU Data version	64.2
ICU Unicode version	12.1

Wedos:

Internationalization support	enabled
ICU version	4.2.1
ICU TZData version	2009j
ICU Unicode version	5.1

I have asked Wedos to migrate the hosting to newer servers, which should support slightly less outdated services:

Internationalization support	enabled
ICU version	50.2
ICU Data version	50.2
ICU Unicode version	6.2

Let’s hope that fixes it.
