In this article we will learn more about a sign that dates back to Ancient Greece and is still used today in many organizations: the Delta symbol.

That’s why so many users get discouraged when looking for the British pound symbol £ (Alt+ 0163) and end up with the lowercase Latin letter acute accent ú (Alt+ 163)-which is also found at Alt+ 0250.It is believed that some symbols do more than convey an identity, but are also a source of power transmission. As an example of a strong symbol that crossed millennia and is, until today, known worldwide is the cross, which represents Christianity. In fact, Alt+ 1 through Alt+ 31 (without the preceding zeroes) are icon symbols (such as happy faces, card suits, astrology icons, etc.) and 176 through 223 are graphic lines and polygons. But the coolest of all are the graphics and icon symbols. In addition to the keyboard characters, you’ll find decimal codes for Greek and Latin letters, accent letters, pronunciation symbols over the alphabet, and mathematical symbols, such as the division and square root operators, the accent grave and circumflex symbols, plus worldwide currency symbols, and more. For example, Alt+ 0251 = û (the Latin small letter u with circumflex symbol above it) while Alt+ 251 = √ (the square root sign)-and so forth until you reach 256, which is the same as 0256 (both produce the pronunciation symbol for an uppercase ‘long’ A that is, Ā).

You can test this yourself by entering both versions of these numbers. Somewhere around the decimal code 256, the preceding zero is no longer necessary.
