OWASP Encoder Comparison Reference Project

Libraries and frameworks encode ASCII characters differently. The OWASP Enterprise Security API (ESAPI) is the reference implementation for the most comprehensive and secure output encoding/escaping. Using this encoder comparison table, you will see how ESAPI exceeds other framework encoders and native encoders.

The OWASP Encoder Comparison Reference Project is a web-based table reference for how ESAPI and other framework and native language encoding methods work against ASCII characters.
