Hi Edward,

Below code works fine please check this out:-

String source = '"[{\\"stage\\":\\"10 - Application\\",\\"oppId\\":\\"2dwd23d231d2w\\",\\"message\\":\\"Opportunity status created.\\"},{\\"stage\\":closedwon,\\"oppId\\":\\"2dwd23d231d2w\\",\\"message\\":\\"Opportunity not found or permission denied.\\"}]"';
String decodedJson = (String)JSON.deserialize(source, String.class);
System.debug('DecodedJson>>>'+decodedJson);

Hope this explanation will resolve your query. Mark it as the best answer if you find it helpful.
Thanks

Hi Edward,

Below is the sample snippet. 
String strText = 'Welcome - to! % $sale&sforce \\ /code # crack %';
strText = strText.replaceAll('[^a-zA-Z0-9\\s+]', '');
System.debug('strText ======> '+strText);

Hi,
There are different ways to remove special characters you can remove all special characters and also remove particular characters.
   
   To remove all characters use: -
   String name = '{B]@i%s*w:?,-a$j#e)e(t! S^a.m}a]l[';
         name = name.replaceAll('[^a-zA-Z0-9\\s+]', '');
     system.debug(name);

   To relace particular character:-
     String str='Rohit & Mohit';
     String str2=str.replace('&','and');
     System.debug(str2);
