Ask yourself do you really need to do this? Remember base64 is primarily intended for representing binary data in ASCII, for storing in a char field in a database or sending via email (where new lines could be injected). Do you really want to take character data, convert it to bytes, then convert it back to character data, this time unreadable and with no hint of what the original encoding was ?
I want to encode a string into base64 and transfer it through a socket and decode it back. But after decoding it gives different answer. Following is my code and result is "77+9x6s=" import ja...
3 The problem is that a character in C# represents a 2-byte UTF-16 character. A cyrillic character is bigger than 255 in UTF-16, so you lose information when converting it to a byte. To convert a string to a byte array, use the Encoding class:
Why was the original string Base64 encoded in the first place?!?? Base64 is usually used to convert binary into a text based portable version for embedding in XML or JSON - possibly to move across a web service layer, not for converting string into encoded string.
How can I decode a string with unicode from http\u00253A\u00252F\u00252Fexample.com to http://example.com with JavaScript? I tried unescape, decodeURI, and decodeURIComponent so I guess the only thing left is string replace.

You can use btoa() and atob() to convert to and from base64 encoding. There appears to be some confusion in the comments regarding what these functions accept/return, so… btoa() accepts a “string” where each character represents an 8-bit byte – if you pass a string containing characters that can’t be represented in 8 bits, it will probably break. This isn’t a problem if you’re ...
In the second case you do the reverse attempting to encode a byte string. Encoding is an operation that converts unicode to a byte string so Python helpfully attempts to convert your byte string to unicode first and, since you didn't give it an ascii string the default ascii decoder fails:
Here, the function will take the binary and decode it (converts binary data to characters using the Python predefined character set and the ignore argument ignores all non-character set data from your binary and finally returns your desired string value.
on converting TO Base64, you must first obtain a byte representation of the string you're trying to encode using the character encoding the consumer of the Base64 string expects. on converting FROM Base64, you must interpret the resultant array of bytes as a string using the same encoding that was used to create the Base64 representation. Examples:
