Assuming that by “English characters” you are simply referring to the 26-character Latin alphabet, this would be an area where I would use regular expressions: ^[a-zA-Z0-9 ]*$ For example: if( Regex.IsMatch(Console.ReadLine(), “^[a-zA-Z0-9]*$”) ) { /* your code */ } The benefit of regular expressions in this case is that all you really care about is … Read more
It won’t make a difference for strings. But in C you can use a char to do math, when it will make a difference. In fact, when working in constrained memory environments, like embedded 8 bit applications a char will often be used to do math, and then it makes a big difference. This is … Read more
>>> c=”\xe7\x9a\x84″.decode(‘utf8′) >>> c u’\u7684’ >>> print c 的 though Unicode encodes it in 16 bits, utf8 breaks it down to 3 bytes.
You just need to add the StringHttpMessageConverter to the template’s message converters: RestTemplate template = new RestTemplate(); template.getMessageConverters() .add(0, new StringHttpMessageConverter(Charset.forName(“UTF-8”))); ResponseEntity<Object> response = template.exchange(endpoint, method, entity, Object.class);
Problem solved by adding BOM at the start of the csv string: var csv = “\ufeff”+CSV;
TL;DR: Pass Unicode to template.render() Encode the rendered unicode result to a bytestring before writing it to a file This had me puzzled for a while. Because you do index_file.write( template.render(index_variables) ) in one statement, that’s basically just one line where Python is concerned, so the traceback you get is misleading: The exception I got … Read more
You don’t need a library beyond the standard one – just use Charset. (You can just use the String constructors and getBytes methods, but personally I don’t like just working with the names of character encodings. Too much room for typos.) EDIT: As pointed out in comments, you can still use Charset instances but have … Read more
Thanks a lot Craig Ringer, works, finally works! You are my new idool now! The steps are: open the cmd SET PGCLIENTENCODING=utf-8 chcp 65001 psql -h your.ip.addr.ess -U postgres
