Could you give me an exemple ?

Give exact filter that you used please.

I'm able to replicate this easily.  Most common message that _doesn't_ filter properly for me and which has a Base64 encoded body, are PayPal payment notifications.

They used to arrive with:
  Content-Transfer-Encoding: quoted-printable
  Content-Type; text/plain; charset="windows-1252"

and those ones would filter just fine.

The new ones now arrive with:
  Content-Transfer-Encoding: base64
  Content-Type: text/plain; charset=UTF-8

and do *not* match at all with the "Body of Message" filtering rule.

My first guess would be that its trying to match/filter based on the raw message body, instead of the decoded message body.

Bug 311633 sounds similar to this, if not a duplicate.

email with the Base64 encoded text: "The file 4207_66496070.zip has been infected with the virus JS/Nemucod.SMK9!tr, and has been removed."

Attaching an example email where a filter intendet to move to Spam if body contains "Nemucod" fails.
This is the filter definition copied from .config/akonadi_mailfilter_agentrc):
[Filter #0]
Applicability=2
AutomaticName=true
ConfigureShortcut=true
ConfigureToolbar=false
Enabled=true
StopProcessingHere=true
ToolbarName=<<body>>: Nemucod
accounts-set=akonadi_imap_resource_0
action-args-0=224
action-name-0=transfer
actions=1
apply-on=check-mail,manual-filtering
contentsA=Nemucod
fieldA=<body>
funcA=contains
identifier=CBlqQTvFEp7ZHSUb
name=<<body>>: Nemucod
operator=and
rules=1

This is from the filter log viewer:
[11:41:08] Esecuzione regole di filtro: (verifica tutti i criteri seguenti) "<body>" <contains> "Nemucod"
[11:41:08] 0 = "<body>" <contains> "Nemucod"
