html - Windows OS displaying unknown character vertical rectangles in browsers -


this question exact duplicate of:

i had interesting issue pop today on couple of websites host. vertical rectangle character displaying (mostly) near
characters in code (though tend use sparingly) on windows machines. i've seen 1 instance vertical character has displayed in middle of paragraph.

i checked site in firefox, chrome , safari on mac , didn't see issues. more interestingly, when log in site backend on windows machine, vertical rectangle character selectable , deletable. no clue why happening.

both sites running on wordpress. i've attached screenshot reference. thanks!

unknown character reference screenshot

that character font doesn't know how render properly. try copy , paste google, , see says is. chances safe remove it, try retyping bit of information without copying , pasting. else, try different font , see if still there. see this more; specifically: the replacement character � (often black diamond white question mark or empty square box) symbol found in unicode standard @ codepoint u+fffd in specials table.

'hasOwnProperty' in javascript -

i use obj.hasownproperty judge whether object has property, when replaced obj[prop] !== undefined , not normal implementation, ask, why behind method can not use it? object.hasownproperty(prop); object[prop] !== undefined; obj[prop] !== undefined wrong 2 reasons: you can explicitly set property undefined , obj[prop] = undefined; . obj.hasownproperty(prop) return true in case. obj[prop] follow prototype chain, return property that's inherited. obj.hasownproperty(prop) returns true if property exists directly in object, returns false inherited properties.
