- Ruby HTML Builder — After checking HTML escaping, generate a ruby element for a reading annotation.
Represent HTML-significant punctuation as text
With quote encoding enabled, “Tom & "Sam"” becomes “Tom & "Sam"”. Decoding that entity string returns the original text.
- Entity conversion is not HTML sanitization, URL encoding or JavaScript-string escaping.
- Attribute values, HTML text and script strings have different safety requirements. Choose an encoding method for the destination context.
Try a use case and check the result
Convert HTML special characters to entity references for literal display.
