If the output encoding format does not contain any character, you can search for the replacement character in the similar encoding; 'ignore': If the output encoding format does not contain a character in the string, it can skip encoding of subsequent characters. Otherwise, output will be interrupted when transcoding fails and an error will be generated. 1. view the input, internal, and output code on the page: Print_r (iconv_get_encoding ("all ")); 2. encode and convert the specified string: Ech
