Text based formats (e.g text file, XML or JSON) were designed to store strings. Recently these is more and more demand storing binary data as well inside text files. For example a file would need to contain image, audio or encrypted data. This is where you use binary data encoding. There are several ways to encoding binary data into a string. Soluling supports the most commonly used encodings.
Base64 (Wikipedia) is the most common binary encoding used when storing binary data into a string. It uses four bytes to store three bytes making it using 33% more space than the binary format. For most application 33% increase is very acceptable. If a text parser support binary encoding the change that it support base64 is highest. You should always use base64 when storing binary data inside string. Soluling supports base64 encoded data.
Base32 (Wikipedia) uses eight bytes to store five bytes. It uses 60% more space than the binary format. Base32 is less efficient than base64 but is has few advantages that makes it quite popular. Soluling supports base32 encoded data.
Base16 (Wikipedia) uses two bytes to store one byte. The encoding is sometimes called hex encoding. It uses twice the space compared to the binary format. Base16 is less efficient than Base64 and base32 but because it is very simple to encode and decode it is commonly used. Soluling supports base16 encoded data.
URL encoding (Wikipedia) uses either one bytes or three bytes to store one byte. On average it uses more than twice the space compared to the binary format. Even it is space inefficient it is sometimes used because encoded strings are URL compatible.
Base85 (Wikipedia) uses marginally less memory than base64. However the difference is not that significant (about 7%). In addition the encoding is complex and it is not compatible to XML and JSON files. Because of these disadvantages base85 is a lot less used than base64. Very few application support it. This is why Soluling does not either support base85. You should use base64 instead.
