As stated in RFC 3492, "Punycode is an instance of a more general algorithm called Bootstring, which allows strings composed from a small set of 'basic' code points to uniquely represent any string of code points drawn from a larger set." Punycode defines parameters for the general Bootstring algorithm to match the characteristics of Unicode text.
With the exception of the information emoji (ℹ), the trademark emoji (™️) and the "m" emoji (Ⓜ️), [citation needed] for an emoji to work as a domain name, it must be converted into so-called "Punycode". Punycode is a character encoding method used for internationalized domain names (IDNs). This representation is used when registering ...
Example of Greek IDN with domain name in non-Latin alphabet: ουτοπία.δπθ.gr (Punycode is xn--kxae4bafwg.xn--pxaix.gr)An internationalized domain name (IDN) is an Internet domain name that contains at least one label displayed in software applications, in whole or in part, in non-Latin script or alphabet [a] or in the Latin alphabet-based characters with diacritics or ligatures.
Converts Unicode character codes, always given in hexadecimal, to their UTF-8 or UTF-16 representation in upper-case hex or decimal. Can also reverse this for UTF-8. The UTF-16 form will accept and pass through unpaired surrogates e.g. {{#invoke:Unicode convert|getUTF8|D835}} → D835.
The fact that Unicode and Punycode strings result in homographs (strings which are different but visually indistinguishable or almost so) is a matter of some concern. Phishing (a class of social engineering exploits) will make use of homographs like "www.paypa1.com" (note: this containst the digit, 1 ("one") rather than the letter, l ("ell").

Combining diacritical marks are also present in many other blocks of Unicode characters. In Unicode, diacritics are always added after the main character (in contrast to some older combining character sets such as ANSEL ), and it is possible to add several diacritics to the same character, including stacked diacritics above and below, though ...
