Question & Answer :
Once I brand a Station petition with a JSON assemblage to my Remainder work I see Contented-kind: exertion/json; charset=utf-eight successful the communication header. With out this header, I acquire an mistake from the work. I tin besides efficiently usage Contented-kind: exertion/json with out the ;charset=utf-eight condition.
What precisely does charset=utf-eight bash ? I cognize it specifies the quality encoding however the work plant good with out it. Does this encoding bounds the characters that tin beryllium successful the communication assemblage?
The header conscionable denotes what the contented is encoded successful. It is not needfully imaginable to deduce the kind of the contented from the contented itself, i.e. you tin’t needfully conscionable expression astatine the contented and cognize what to bash with it. That’s what HTTP headers are for, they archer the recipient what benignant of contented they’re (supposedly) dealing with.
Contented-kind: exertion/json; charset=utf-eight designates the contented to beryllium successful JSON format, encoded successful the UTF-eight quality encoding. Designating the encoding is slightly redundant for JSON, since the default (lone?) encoding for JSON is UTF-eight. Truthful successful this lawsuit the receiving server seemingly is blessed realizing that it’s dealing with JSON and assumes that the encoding is UTF-eight by default, that’s wherefore it plant with oregon with out the header.
Does this encoding bounds the characters that tin beryllium successful the communication assemblage?
Nary. You tin direct thing you privation successful the header and the assemblage. However, if the 2 don’t lucifer, you whitethorn acquire incorrect outcomes. If you specify successful the header that the contented is UTF-eight encoded however you’re really sending Latin1 encoded contented, the receiver whitethorn food rubbish information, attempting to construe Latin1 encoded information arsenic UTF-eight. If of class you specify that you’re sending Latin1 encoded information and you’re really doing truthful, past sure, you’re constricted to the 256 characters you tin encode successful Latin1.
