### What happened?
I have encountered an issue when using Apache PLC4X to connect to an OPC UA
server. The problem occurs when the password contains an exclamation mark (!).
The connection fails with the following error:

I have successfully connected to other OPC UA servers using anonymous
authentication and username/password authentication. However, when the password
contains special characters (like !), authentication fails.
Another related issue occurs when reading NodeIds that contain single quotes
(') or double quotes (") in their identifier. I cannot read values from these
nodes, and escaping the characters does not help.
For example, I cannot read the following NodeId(copied from UaExpert) :
ns=3;s="Stationen".
When attempting to read it, I receive the following error:
`2025-03-27 10:52:07.280 [nioEventLoopGroup-3-1] ERROR
o.a.p.j.o.p.OpcuaProtocolLogic - Error while reading value from OPC UA server

**Additional Information:**
Using UaExpert, both authentication and reading the above NodeId work
without any issues.
It seems like special characters in the connection string parameters are not
being handled correctly.
**Steps to Reproduce:**
Try to connect to an OPC UA server with a password containing !.
Try to read a NodeId containing double quotes (") in its identifier (e.g.,
ns=3;s="Stationen").
**Environment:**
Java version: 21
OPC UA Server: SecurityPolicy = None
