Since entity number 8203 is not an official W3C entity (reference: it does not render properly in some browsers (shows up as a box with an X).

Test script:
Use Opera in Linux to test.  Ex:

I believe this belongs to Opera's bug tracker, as this is neither bug in PHP nor in PHP's website.

"Official W3C entities" refer to named entities, not character codes. #8203 is a valid code for character U+200B (which should not be rendered at all, so it's not a typeface issue).

AFAIK, the "zero width space" may appear as an "unknown character" in some browsers, this is not incorrect regarding the Unicode specification. It may also be displayed as a space in other cases, like justified text.

There are aternatives to the entity ​ that fix this wrong behaviour, at least with Opera/Linux. They are more portable than the current numerical entity.

1. Use the tag <wbr> (official since HTML5, but cross-browser since a long time, see ).
2. Use a soft hyphen &shy; (this changes slightly the behaviour, as a hyphen will appear when the word is split).

While replacing the ZERO WIDTH SPACE with <wbr> wouldn't be
particularly hard[1], I wonder whether that is still relevant.
