Zend_Framework - No region found within the locale 'zh'

Question

I've had a look around the Internet and can't seem to find a solution to the problem I'm experiencing. I'm trying to use Zend_Currency to get the currency for China like so:

$currency = new Zend_Currency('CN');

However, I keep receiving the following error:

Fatal error: Uncaught exception 'Zend_Currency_Exception' with message 'No region found within the locale 'zh'' in /Library/WebServer/Documents/vendor/zendframework/zendframework1/library/Zend/Currency.php on line 561

This is on a fresh install of Zend Framework 1.12.3, and as far as I'm aware I'm not doing anything incorrect here. From the error I can see that Zend has matched the country code to the locale.

This is a problem as my application relies on obtaining currency information from a country code. I have no issues with GB, US etc.

I've had a look in Zend/Locale/Data and can confirm the zh.xml, zh_CN.xml locale files are there, but I'll admit I'm not 100% what I'm looking for in each!

Anyone have any ideas about what the issue is and how I might go about fixing it?

Thanks

EDIT:

This is an edit to reflect comment discussion.

It seems that Zend_Locale returns zh when given the country code CN, rather than the expected string zh_CN. This means that I am unable to find anything consistent that I can pass to Zend_Currency to avoid errors.

I think this is a bug in Zend mismanaging the CN region.
In fact, if I'm not mistaken, the name of the locale is zh_Hans_CN and when it manages the CN region Zend see if it is part of the variable $_localeData (in Zend/Locale.php file) and as this is not the case, it decomposes zh_Hans_CN and keeps only zh he does not know either.

If you want to keep the same principle as $currency = new Zend_Currency('CN');
you can try it:

Zend_Locale::getLocaleToTerritory('CN');

will retrieve the correct locale by default. (like 'US' give 'en_US')
Which gives:

$currency = new Zend_Currency(Zend_Locale::getLocaleToTerritory('CN'));
