问题 I'm a .NET developer and was asked to do an application that converts html files to ANSI in C#. ANSI is necessary because the converted files will run on a Visual Fox Pro application. The basic logic is ready the problem is with the conversion itself. I've tried this code: http://social.msdn.microsoft.com/Forums/pt-BR/026ddda3-9bd1-4502-b445-e2a1cc88345d/convert-file-from-utf8-to-ansi?forum=csharplanguage but when I checked it on editplus the file is still not converted to ANSI and even worst

问题 I've seen lots of places say: The maximum number of characters is 255. where characters are ASCII. Is there a technical reason for that? EDIT: I know ASCII is represented by 8 bits and so there're 256 different characters. The question is why do they specify the maximum NUMBER of characters (with duplicates) is 255. 回答1: I assume the limit you're referring to is on the length of a string of ASCII characters. The limit occurs due to an optimization technique where smaller strings are stored

问题 Using NodeJS v5.6 I created a file called read-stream.js : const fs = require('fs'), stream = fs.createReadStream(process.argv[2]); stream.on('data', function(chunk) { process.stdout.write(chunk); }); stream.on('error', function(err) { process.stderr.write("ERROR: " + err.message + "\n"); }); and a data file in plain text called target.txt : hello world this is the second line If I do node read-stream.js target.txt the contents of target.txt are printed normally on my console and all is well.
