Mail subject utf8 error

[NamPNQ]

Subject =?utf-8?q?I=27some_test?=

Hi,

I'm facing a similar issue when trying to fetch mails from the Api (v2).
Performing a query on /api/v2/search using containing on the subject of a mail gives an empty result.

For instance I search: 'containing' => 'Your free product', but in fact the subject appears as Your free =?utf-8?Q?product=0A?= when fetching all mails.

Could it be possible to do something for clean up the subject as it is done for the web interface, in order to allow performing containing queries on?
Thank you
