fix(compiler): add mappings for all HTML entities #42818
Closed
Conversation
Angular inserts text either through text nodes (`document.createTextNode`) or using `textContent`, but the drawback of doing so is that HTML entities won't be decoded. In order to work around it, the compiler has some logic that maps the entities to their unicode representation which can safely be inserted. The problem is that our current mapping is arbitrarily limited which means that some entities will be mapped while others will throw an error, even though they're valid. These changes expand the list to cover all entities that are supported by the HTML spec. Fixes #41186.
