Best way to decode hex sequence of unicode characters to string

由 一个人想着一个人 提交于 2019-12-21 17:54:29
问题 I'm working with C# .Net I would like to know how to convert a Unicode form string like "\u1D0EC" (note that it's above "\uFFFF") to it's symbol... "𝃬" Thanks For Advance!!! 回答1: That Unicode codepoint is encoded in UTF32. .NET and Windows encode Unicode in UTF16, you'll have to translate. UTF16 uses "surrogate pairs" to handle codepoints above 0xffff, a similar kind of approach as UTF8. The first code of the pair is 0xd800..dbff, the second code is 0xdc00..dfff. Try this sample code to see

Is it possible to decode EventValidation and ViewState in ASP.NET?

问题 How to decode the ASP.NET EventValidation and ViewState? 回答1: I answered a similar question recently, Getting values from viewstate using JQuery?. Basically, by default ViewState is just Base64-encoded, so you can decode it as long as the administrator hasn't configured the site to encrypt it. Quoting from my previous answer: If you are writing the control for your own consumption and you only need to read from ViewState , you could do so, but I wouldn't recommend it unless you find a well

Web Audio API: decodeAudioData doesn't decode opus in Chrome

由 旧城冷巷雨未停 提交于 2019-12-21 05:46:13
问题 I'm currently trying to make Opus packets work with Web Audio API. The problem is however, while it should be natively supported by FireFox and Chrome, only FireFox can decode a stream of OPUS samples using decodeAudioData from the Web Audio API. Chrome does recognize the file when I drag the opus file into the browser and it also does play it! So I'm wondering that I may be doing something wrong here causing failure in Chrome. Then I used some sample code from http://awm.jp/~yoya/js/audio

InputStreamReader buffering issue

由 旧街凉风 提交于 2019-12-20 13:32:25
问题 I am reading data from a file that has, unfortunately, two types of character encoding. There is a header and a body. The header is always in ASCII and defines the character set that the body is encoded in. The header is not fixed length and must be run through a parser to determine its content/length. The file may also be quite large so I need to avoid bring the entire content into memory. So I started off with a single InputStream. I wrap it initially with an InputStreamReader with ASCII
