Base64 can be used if it is really necessary to use strings to represent bytes. Note that you can store byte arrays in a database, so you don't need a string for that purpose, e.g., in MySQL you might use the VARBINARY database type.

python - Encode byte string in utf8 - Stack Overflow

WebUTF-8 is a sparse encoding: a large fraction of possible byte combinations do not result in valid UTF-8 text. Binary data and text in any other encoding are likely to contain byte sequences that are invalid as UTF-8. WebUTF-8 is a Unicode encoding that represents each code point as a sequence of one to four bytes. Unlike the UTF-16 and UTF-32 encodings, the UTF-8 encoding does not require "endianness"; the encoding scheme is the same regardless of whether the processor is big-endian or little-endian. UTF8Encoding corresponds to the Windows code page 65001. WebSince UTF-8 is interpreted as a sequence of bytes, there is no endian problem as there is for encoding forms that use 16-bit or 32-bit code units. Where a BOM is used with UTF-8, it is only used as an encoding signature to distinguish UTF-8 from other encodings — it has nothing to do with byte order. [AF] craziest sports fights
