B4R strings are different than in other B4X tools. The reasons for these differences are: 1. Very limited memory. 2. Lack of Unicode encoders. A String object in B4R is the same as C char* string. It is an array of bytes with an additional zero byte at the end. The requirement of the last zero byte

A bit. You can convert strings to bytes with any encoding you like and then back to a string. Once it is a String object, it doesn't have any encoding.
link: Worth reading: https://www.b4x.com/glossary/unicode-utf8/ Strings do not have encoding. Only raw bytes (such as files).

This code is no longer needed. Use File.WriteBytes / ReadBytes. Write an array of bytes to a file and read a file into an array of bytes. Sub BytesToFile (Dir As String, FileName As String, Data() As Byte) Dim out As OutputStream = File.OpenOutput(Dir, FileName, False) out.WriteBytes(Data,

link: You can use BytesToFile from the first post to save bytes to a file. It will be a binary file not text file. If you like to create a text file then yo

You shouldn't convert bytes to string unless the bytes actually represent string. The correct solution should be based on B4XBytesBuilder from B4XCollections library.

CSVParser (B4X) - B4X class that reads and writes CSV files. It can handle non-UTF8 encoding and can be customized to better handle errors. Base64 encoding It is a common mistake to treat raw bytes as strings. It doesn't work. If you want to convert raw bytes to a string then you need to use the B

The bytes do not represent a string. Maybe the baudrate is incorrect. You don't need to do anything special to convert bytes to string.

B4XSerializator is only relevant if both sides use it. client.Publish2("hello", "CLIC".GetBytes("utf8"), 0, False) Use BytesToString keyword to convert an array of bytes to string.

It depends on what you are trying to send. If you want to send the string then call GetBytes to convert it to bytes. If the string itself is in hex format then use ByteConverter.HexToBytes (or BytesFromHex) to convert it to an array of bytes.

Base 64 is the correct way to convert "random bytes" to string. Another simple option is to use KVS (2) which supports encryption as well, though it will not create a text file (why does it matter?).
