Drupal has a flexible language management, and we may create custom language to better match the context.
In Mandarin, there are more granularity to describe a language with the script style.
For instance, there are zh-hant (Traditional Chinese) and zh-hans (Simplified Chinese) for two types of script style.
In terms of the country, region and dialects, zh-hant can be further divided into zh-hant-tw (Traditional Chinese with terms used in Taiwan) and zh-hant-hk (Traditional Chinese with terms used in Taiwan). zh-hans can be divided into zh-hans-cn and zh-hans-sg, etc.
The existing processDrupalSetting() in the class KlaroHelper process the langcode with a easy way, that explode the text and only get the first part of text before the first hyphen "-" character. When there are two hyphens, it conflicts with the way Klaro JS interprets the langcode. Klaro uses Regex to get the first segment of the langcode only when it has one hyphen, and return any other case as is.
This causes the Klaro unable to find the translation.
It is better to make the code more consistent with the JS and improve the flexibility.

Code
Refactor language code extraction in KlaroHelper to use regex for improved accuracy. Also assign the lang in Klaro config, so Klaro uses the translation the module provides.
