Could you elaborate in which circumstances it will cause broken output?

Returning empty strings ALSO has the risk of broken output. Even worse, broken output is basically guaranteed. ------------------------------------------------------------------------ [2015-04-14 19:52:03] yohgaki@php.net Replacing any invalid byte sequence in string has risk of broken output. i.e. Broken html structures, etc. If you would not want to have empty outputs from htmlspecialchars, validate all of your inputs. You can replace invalid multibyte sequence optionally. i.e. Use mb_convert_encoding(). This is the optimal way to handle text. ------------------------------------------------------------------------ [2015-04-14 17:50:31] olafvdspek at gmail dot com Description: ------------ Could you default to ENT_SUBSTITUTE for htmlspecialchars()?
