character decoding failed error

Question

I'm unable to understand why there occurs character decoding failed warning at my server.

May 19, 2012 2:56:57 AM org.apache.tomcat.util.http.Parameters processParameters

WARNING: Parameters: Character decoding failed. Parameter 'width' with value '100%' has been ignored. Note that the name and value quoted here may corrupted due to the failed decoding. Use debug level logging to see the original, non-corrupted values.

Answer 1

Well, the % at the end signifies a bad encoding. If properly encoded, it should really be followed by two hexadecimal characters.

Answer 2

if 'Parameters: Character decoding failed' warning include % issue then we can use given below code, no need to do any thing. I am using this in my ajax function.

var productPromoCodeIdParam = productPromoCodeId.replace('%','%25');
