Issue with REST API Returning Modified Text in Item Description

Hello,
I've encountered an issue with the REST API where the description of a requirement item is returned incorrectly when retrieved via API call. After entering "adler32_z" into the description of an item and saving it, I used the REST API to fetch the item's details with the following GET request: GET /api/v3/items/%item_id%/fields.
Expectedly, I hoped to see "adler32_z" as the value of the Description field. However, the response returned "adler32~_z" instead. Here is the response I received:

This issue appears to be specific to descriptions containing "adler32", as other descriptions seem to be fetched correctly. Could you please help me understand why this alteration in the text is happening? Is there a specific parsing or encoding rule that might be affecting text containing "adler32"?
Thank you for your assistance.
