This service works as a simple convertor. It can convert common text in utf-8 encoding to its binary representation by clicking the encode button. The decode button can be used to vice versa conversion. Thanks to utf-8 compatibility to ACSII this service converts ASCII characters correctly too.
Unicode is a variable-length character encoding and is compatible with ASCII. The original specification allowed for sequences of up to six bytes but it was reduced by RFC to four later. The bits of a Unicode character are distributed into the lower bit positions inside the UTF-8 bytes, with the lowest bit going into the last bit of the last byte.
Character code U+FEFF on the beginning of data stream stands for Byte Order Mark. It's sometimes used as signature defining the byte order in plaintext files. In fact there are five correct forms of this BOM which depends on Unicode version. Under some protocols, use of BOM may be prohibited or mandatory. According to this some applications aren't able to work correctly with Unicode, sometimes.
It was created for study purpose. Few of my friends was looking for similar service and I found it useful then.

New line is a charater, too. However on Windows machines, there is also a carriage return character before a line feed character. The line feed is is used as new line character on UNIX and other operating systems.
