AWS CloudFormation keys not accepting special characters

I have noticed that AWS CloudFormation does not like special characters.

When I update a key:value pair in our pipeline.yml file with special char e.g. PAR_FTP_PASS: ^XoN*H89Ie!rhpl!wan=Jcyo6mo, I see the following error:

parameters[5] ParameterKey, ParameterValue or UsePreviousValue expected

I am able to update the value through the AWS CloudFormation UI.

It seems like the issue is to do with AWS CloudFOrmation parsing the yml file.

Is there a workaround with this issue?

AWS Tags have some restrictions on what they can contain, see here: https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/Using_Tags.html#tag-restrictions

A key note which can catch people out is: "Although EC2 allows for any character in its tags, other services are more restrictive. The allowed characters across services are: letters, numbers, and spaces representable in UTF-8, and the following characters: + - = . _ : / @."

So I'd check if the service you are adding this onto can support that string.
