Problem:
You are trying to translate content on your site, but the translation process is stuck and the changes cannot be seen on the website.
Solution:
We’ve investigated the issue affecting your translation jobs and identified the root cause.
The problem appears to be related to your server’s character encoding settings. Specifically, it looks like the server’s locale is not explicitly set, and it defaults to an older encoding format (ISO-8859-1) instead of the required UTF-8 encoding. UTF-8 is essential for correctly handling Chinese characters.
As a result, when a string such as 圖示清單：文字 (encoded in UTF-8) is processed using the PHP function ucwords, the encoding unexpectedly switches to ISO-8859-1. This causes issues in our logic when generating the XLIFF files used to submit translation jobs. Essentially, this encoding mismatch leads to corrupted data in the translation files, which then prevents translation jobs from being processed correctly and causes them to get stuck (specifically in status 6).
The XLIFF file being generated on your server is improperly encoded with ISO-8859-1.
This leads to corrupted translation units, with the file being abruptly cut off.
The issue stems from the labelize() function in the WPML plugin, which uses ucwords()—a function not suitable for non-ASCII characters like Chinese.
Workaround solution :
We’ve modified our internal utility function to use mb_convert_case() instead of ucwords(), which correctly handles UTF-8 encoding. This change resolves the issue on your site, allowing translation jobs to complete successfully.
Here’s the updated function. Please note that this change was made directly within the WPML plugin files (sitepress-multilingual-cms/classes/utilities/Labels.php)
From :
1 2 3 4 5 6 7 8 9 10 11 | public static function labelize( $string ) {
return ucwords(
strtr(
$string,
[
'-' => ' ',
'_' => ' ',
]
)
);
}
|
To :
1 2 3 4 5 6 7 8 9 10 11 12 13 | public static function labelize( $string ) {
return mb_convert_case(
strtr(
$string,
[
'-' => ' ',
'_' => ' ',
]
),
MB_CASE_TITLE,
'UTF-8'
);
}

Anyway, our developers have fixed this and an update will be available in the next release.
