Encoding binary into unicode

hope this fix your issue The most optimal solution would be to store binary in a binary column. So you mean the most optimal encoding within the constraints of this suboptimal scenario?
Just go for base64, it's safe.

Does that help I could not reproduce the problem, but the easiest solution is probably to select the strings file in Xcode and set the "Text Encoding" to "UTF-16" in the File inspector.

DateTime encryption and decryption, System.Text.Encoding.Unicode.GetBytes and System.Text.Encoding.Unicode.GetString not

To fix this issue Not every sequence of bytes are valid in unicode. System.Text.Encoding.Unicode.GetString ignores such sequences. Base64 strings was designed to convert any sequence of bytes in string. In .net you work with base64 strings via Convert class through methods such as ToBase64String(Byte[]) and FromBase64String(string).

Get a Null-Terminated String when using Encoding.ANSI or Encoding.Unicode

I wish did fix the issue. As far as I remember, null-termination is a specific thing to C/C++'y languages/platforms. Unicode and ANSI encodings does not specify any requirement for the string to be null-terminated, nor does the C#/CLR platform. You can't expect them to include that extra character. So you will probably have a hard time making those classes emit that from yours 5-character "Hello" string.
However, in C#/CLR, strings can contain null characters.
code :
string a = "Hello\0";
string a = "Hello";
a += "\0"; // if you really can't have the \0 at first time, you can simply add it

Encoding=ASCII; and Encoding=UNICODE; do not work in an Npgsql 3 connection string

By : Kal Davies

I hope this helps you . You probably have an old Npgsql connection string. Encoding=ASCII or Encoding=UNICODE will no longer work when using current (3.2.0) Npgsql to access current (9.6.1) PostgreSQL.
Solution: just remove Encoding=xxx completely and everything works!

help you fix your problem It's (part of) a URL, so System.Web.HttpUtility.UrlDecode should do the trick.
code :
string value = System.Web.HttpUtility.UrlDecode("%u0633%u0644%u0627%u0645");
// value is: سلام
