Most string operations for Unicode can be coded with the same logic used for handling the Windows character set. The difference is that the basic unit of operation is a 16-bit quantity instead of an 8-bit one. The header files provide a number of type definitions that make it easy to create sources that can be compiled for Unicode or the Windows character set.

When the page says Unicode, Internet Explorer will activate Unicode. However, when the page says Arial, Internet Explorer will display Arial. While Arial does include e. g. basic Greek and Cyrillic, it does not include e. g. IPA extensions. These are displayed in Arial anyway when the page says so – that is, they are displayed as the famous rectangles. David Marjanović | david.marjanovic_at_gmx.at | 00:44 | 2006/5/16

In text processing, Unicode takes the role of providing a unique code point — a number, not a glyph — for each character. In other words, Unicode represents a character in an abstract way and leaves the visual rendering (size, shape, font or style) to other software, such as a web browser or word processor. This simple aim becomes complicated... by concessions made by Unicode's designers in the hope of encouraging a more rapid adoption of Unicode.

If you have Microsoft Office but do not see the snowman, you can install the Arial Unicode MS font. The Arial Unicode MS font is installed as part of the Microsoft Office Setup and is part of the International Support features. To install the Arial Unicode MS font, follow these steps:

[One] concept to be familiar with as you work with Unicode is that of byte- order marks. A BOM is used to indicate how a processor places serialized text into a sequence of bytes. If the least significant byte is placed in the initial position, this is referred to as "little-endian," whereas if the most significant byte is placed in the initial position, the method is known as "big-endian." A BOM can ... be used as a reference to identify the encoding of the text file. Notepad, for example, adds the BOM to the beginning of each file, depending on the encoding used in saving the file. This signature will allow Notepad to reopen the file later.

Unicode can be useful in web pages when the @ symbol displayed unicode equivalent of @ is posted to a web page to stop the spambot harvesting software from gathering useful email addresses from web pages. This trick is not always effective but does stop some harvesting software from recognizing those unicode symbols as valid email addresses.
