/**
 * WAW036: Non-ASCII Characters in EC2/IAM String Properties
 *
 * EC2, IAM, CloudWatch, and other AWS services only accept ASCII 0x20–0x7E in
 * description, name, and label fields. Non-ASCII characters (em-dashes, curly
 * quotes, accented letters, etc.) cause the changeset to fail at EarlyValidation
 * with an opaque "Invalid parameter" error that doesn't name the offending property.
 *
 * Properties checked (all must be plain ASCII strings):
 *   - AWS::EC2::SecurityGroup           GroupDescription
 *   - AWS::EC2::LaunchTemplate          LaunchTemplateName
 *   - AWS::IAM::Role                    RoleName
 *   - AWS::Lambda::Function             FunctionName
 *   - AWS::RDS::DBSubnetGroup           DBSubnetGroupDescription
 *   - AWS::CloudWatch::Alarm            AlarmDescription, AlarmName
 *   - AWS::AutoScaling::AutoScalingGroup AutoScalingGroupName
