character-encoding

问题 Is it possible to read image as text and send it over network? Is yes, then how can we do this? 回答1: You could base64 encode the image to produce a (text) string. Apache Commons Codec has a Base64 implementation that you can easily use: import org.apache.commons.codec.binary.Base64; // Read the byte array from file, DB, etc byte[] imageByteArray = getImageByteArray(); String base64Image = Base64.encodeBase64String(imageByteArray); 来源： https://stackoverflow.com/questions/6484002/sending-image

问题 For example, say I have the following xml in a string: <?xml version="1.0" encoding="UTF-8"?> <Stuff /> If I try to insert this into a SQL Server 2005 database table with an Xml column, I'll get the following error (I'm using EF 4.1, but I don't think that matters): XML parsing: line 1, character 38, unable to switch the encoding After doing some research, I learned that SQL Server expects the xml to be UTF-16. How do I convert it? 回答1: My first few attempts involved streams, byte arrays and

问题 I'm using ObjectMapper to serialize posts in my system to json. These posts contain entries from all over the world and contain utf-8 characters. The problem is that the ObjectMapper doesn't seem to be handling these characters properly. For example, the string "Musée d'Orsay" gets serialized as "Mus?©e d'Orsay". Here's my code that's doing the serialization: public static String toJson(List<Post> posts) { ObjectMapper objectMapper = new ObjectMapper() .configure(Feature.USE_ANNOTATIONS, true

问题 I use DOMDocument to manipulate html and php 7. The problem is that text shows good on page (cyrillic), but when I go to "See HTML page source", it is not good . It shows like this: Здесь осн What might be wrong? <meta> charset is utf-8. My code: $dom = new DOMDocument(); if (@$dom->loadHTML(mb_convert_encoding("<div>$body</div>", 'HTML-ENTITIES', 'UTF-8'), LIBXML_HTML_NOIMPLIED | LIBXML_HTML_NODEFDTD)) { // https://stackoverflow.com/questions/29493678/loadhtml-libxml-html-noimplied-on-an

问题 I'm trying to prepare a demo html page with mixed english and arabic content. Basically it contains a small table with english phrases on the left, and the arabic translation on the right side. Because I don't understand arabic, I took the first three characters of the arabic alphabet from the Unicode reference. First attempt, using the character entities (ا ب ت): it works (display: ا ب ت). The I tried to enter the arabic characters directly in the document. To enable this, I saved the

问题 In Excel, how can I convert the contents of a cell which includes accented characters, curly quotes etc into either HTML for the same characters, OR a transliterated plaintext version? We have an XLS document which contains some "high" characters. The data has been pulled in via a DB connection, and it appears that Excel is correctly handling individual cells (or rows) being in different codepages. When we export this data to a CSV, some high characters are not correctly rendered - it appears

问题 once again I am experiencing problems with encodings when trying to zip files in a PHP application. Here is the deal, whenever the file name contains special characters, i.e.: 'eñeìá.html', I am not able to zip it right.. the result of zipping it with the php function AddFile is 'e+¦e+¼+í.html' The problematic line is the following: $zip->addFile($file_to_add_path, $file_to_add->getFilename()); I have already tried using iconv, utf8_decode/encode, etc. but no luck yet. The closer I got was

问题 I have a strange question with PHP app connecting to a SOAP 1.2+WSDL service: Previous information: Apache server 2.4 with php5-fcgi module. I'm working on a client for a SOAP service, and I can do some request for the service. The request took some time to complete.

问题 I'm just learning about C and got an assignment where we have to translate plain text into morse code and back. (I am mostly familiar with Java so bear with me on the terms I use). To do this, I have an array with the strings for all letters. char *letters[] = { ".- ", "-... ", "-.-. ", "-.. ", ".", "..-." etc I wrote a function for returning the position of the desired letter. int letter_nr(unsigned char c) { return c-97; } This is working, but the assignment specifications require the
