Java8 BASE64 Codec Java has always lacked the BASE64 encoding API, which is often used by third-party API implementations in project development. However, Java 8 implements the BASE64 codec API, which contains the Java.util package. I'm going to do an introduction to the Java 8 BASE64 API below.

When using Python to write files or writing network data streams to local files, the following error occurs in most cases: UnicodeEncodeError: 'gbk' codec can't encode character '\ xa0' in position... this problem. There are many similar files on the network that tell you how to solve this problem, but it is nothing more th
Background:in making a dicom Web Service, where Wado-rs needs to parse Transfersyntax, then it uses the Dicomfile.changetransfersyntax method in fo-dicom. code similar to:var df = dicomfile.open (SamplesDir + @ "\user submitted\overlays.dcm");df = df.

Today to help others solve a problem about BASE64 codec, unexpectedly found that Delphi with the BASE64 codec unit, called ENCDDECD, the name is very awkward and not intuitive, estimated that this is a very few people pay attention to and know the reason.This unit provides two sets of four public functions:Encoding and decoding of convection:Procedure Encodestream (Input, Output:tstream); CodingProcedure De
Usually use Base64 this codec way to convert binary data into a visible string format, which is what we often say, 10 dollars a string of the kind, ^_^.Android Android.util package directly provides a fully functional Base64 class for us to use, the following shows how to make a picture of Base64 codec.1. Find the picture Public void onencodeclicked(View view) {//select PictureIntent Intent =NewIntent (); I
After years of verification, the code-driven Linear Prediction Model (CELP, Code Excited Linear Prediction) is one of the most popular speech codec models that are used to reconstruct speech quality. Speex and other CELP codecs are based on the CELP model. What is the main idea of the CELP model?
1. Use the linear prediction (LP, linear prediction) model to model the channel system;
2. Based on the speech generation principle, an adaptive CAPTCHA and

In Python, the processing of Chinese characters has always been a headache, a word is garbled, and the cause of garbled is not the same, sometimes Python itself default encoder settings are not correct, and sometimes the use of the IDE decoder is not correct, There are sometimes terminal terminal decoder is not correct, the same code in the Python2 on the normal operation, Python3 on it, anyway, there are many reasons for garbled, here are some of the bloggers have encountered some errors and so
When writing a file using Python, or when writing a network stream to a local file, in most cases you will encounter: Unicodeencodeerror: ' GBK ' codec can ' t encode character ' \xa0 ' in position ... The problem. There are a lot of similar files on the network about how to solve this problem, but nothing is encode,decode related, is this the real cause of the problem? No. Many times, we used decode and encode, tried all kinds of code, utf8,utf-8,gbk
