# Feature: #69730 - Introduce uniqueId generator

See [forge#69730](https://forge.typo3.org/issues/69730)

## Description

A new method `getUniqueId()` has been added to the StringUtility class.
Now there is a common way to generate an unique identifier which can be
used even in HTML tag attributes as it removes the invalid dot character.

```php
$uniqueId = \TYPO3\CMS\Core\Utility\StringUtility::getUniqueId('Prefix');
```

## Impact

No need to remove the dot manually anymore.
