All Application Manual Name SummaryHelp

Availability::- use_module(library(http/http_header)).
Sourcehttp_update_encoding(+HeaderIn, -Encoding, -HeaderOut)
Allow for rewrite of the header, adjusting the encoding. We distinguish three options. If the user announces‘text’, we always use UTF-8 encoding. If the user announces charset=utf-8 we use UTF-8 and otherwise we use octet (raw) encoding. Alternatively we could dynamically choose for ASCII, ISO-Latin-1 or UTF-8.
