Symfony version(s) affected

5.4.22

Description

There is an error when generating Subject header containing two spaces. Both spaces got deleted.

From
Balíček k Vaší žádostič.O42300203 právě dorazil
becomes:
Balíček k Vaší žádostič.O42300203právě dorazil

Screenshot_20230516_134350

How to reproduce

> (new \Symfony\Component\Mime\Header\UnstructuredHeader('Subject', 'Balíček k Vaší žádostič.O42300203  právě dorazil'))->toString()
= """
  Subject: =?utf-8?Q?Bal=C3=AD=C4=8Dek?= k\r\n
   =?utf-8?Q?Va=C5=A1=C3=AD_=C5=BE=C3=A1dosti=C4=8D=2EO42300203?= \r\n
   =?utf-8?Q?pr=C3=A1v=C4=9B?= dorazil
  """

Two spaces after O42300203 get lost. Both Gmail and https://dencode.com/en/string/quoted-printable decodes resulting encoded subject header as without any space after O42300203.

It looks like the same problem with older issue in swiftmailer, but it's still not fixed in Symfony too: swiftmailer/swiftmailer#601

based on the closing date, I don't think the issue was ever fixed in Swiftmailer: the issue was closed the day the repo was archived, not because of a fix.

If anyone has a fix for the issue, PRs are welcome.

Yes, it was not fixed and is not fixed there in SF too. But it looks like not so simple to fix it...
