How to do formatting when translating static text in Yii2?

Question

Yii

In code: In file ru/frontend.php
Yii::t('frontend', 'Personal Data')

return[
'Personal Data' => 'Личные данные',
];

How can you bold the word Data and data in both cases...
For example: 'Personal Data' => 'Personal data', then everything is fine in Russian, but even if in the en/frontend file:

'Personal Data' => 'Personal <strong>Data</strong>',

there is a line for translation, it still does not take it into account ...
en - set as the default language.

Answer 1

the manual says:

You can configure application languages ​​in the application configuration like the following:
return [
// set target language to be Russian
'language' => 'ru-RU',
// set source language to be English
'sourceLanguage' => 'en- US',
......
];
The default value for the source language is en-US, meaning US English.

Try to make sure that all the settings are done correctly, and you set the values ​​for en-US, and then use the English not en-US, but en
