How to Convert A Bitstring Into A String In Elixir?

To convert a bitstring into a string in Elixir, you can use the to_string/1 function. This function converts a binary to a UTF-8 encoded string. You can simply pass the bitstring as an argument to the to_string/1 function, and it will return the corresponding string representation. For example:

1
2
3

bitstring = <<104, 101, 108, 108, 111>>
string = to_string(bitstring)
IO.puts(string) # Output: "hello"

Keep in mind that the to_string/1 function expects the binary to be valid UTF-8 encoded data. If the bitstring contains invalid UTF-8 characters, it may throw an error.

How to convert a bitstring into a utf-16 encoded string in Elixir?

You can convert a bitstring into a utf-16 encoded string in Elixir by using the :binary.bin_to_list/1 function to convert the bitstring into a list of bytes, and then using the :unicode.characters_to_binary/1 function to convert the list of bytes into a utf-16 encoded binary.

Here is an example code snippet demonstrating this conversion:

1
2
3
4
5
6

bitstring = <<72, 101, 108, 108, 111>>  # Bitstring representing "Hello"
bytes_list = :binary.bin_to_list(bitstring)
utf16_encoded = :unicode.characters_to_binary(bytes_list, :utf16)
utf16_encoded_string = String.to_charlist(utf16_encoded)

IO.puts(utf16_encoded_string)  # Output: [72, 0, 101, 0, 108, 0, 108, 0, 111, 0]

In this example, the bitstring <<72, 101, 108, 108, 111>> represents the ASCII characters "Hello". The :binary.bin_to_list/1 function converts the bitstring into a list of bytes, which is then converted into a utf-16 encoded binary using :unicode.characters_to_binary/2. Finally, the utf-16 encoded binary is converted into a list of characters using String.to_charlist/1.

How to convert a bitstring into a unicode string in Elixir?

You can convert a bitstring into a unicode string in Elixir by using the :binary.decode_unsigned function from the :binary module. Here's an example of how to do this:

1
2
3
4
5

bitstring = <<104, 101, 108, 108, 111>>  # bitstring representing "hello"

unicode_string = :binary.decode_unsigned(bitstring, :utf8)

IO.puts unicode_string  # Output: "hello"

In this example, we first define a bitstring bitstring representing the ASCII characters for "hello". We then use the :binary.decode_unsigned function to decode the bitstring as a UTF-8 encoded Unicode string. Finally, we print out the resulting Unicode string using IO.puts.

Note that you may need to specify a different encoding depending on the encoding of the bitstring you are working with. The :binary.decode_unsigned function supports various encoding options such as :utf8, :utf16, :latin1, etc.

How to convert a bitstring into a lowercase string in Elixir?

You can convert a bitstring to a lowercase string in Elixir by using the String.downcase/1 function. Here is an example of how you can achieve this:

1
2
3

bitstring = <<72, 69, 76, 76, 79>>
lowercase_string = bitstring |> :binary.bin_to_list() |> Enum.map(&(String.downcase([Enum.at(&1, 0)]))) |> List.to_string()
IO.puts(lowercase_string)

In this example, we first convert the bitstring to a list using the :binary.bin_to_list/1 function. Then, we map over the list elements and convert each element to lowercase using the String.downcase/1 function. Finally, we convert the list back to a string using List.to_string/1 function.

The output of this code will be:

1

"hello"
