How are special characters represented in HTML?
Representing special characters in HTML can be a bit of a challenge, as some text editors may not be able to render them properly. However, with the right code, it's possible to display any kind of character, including those with diacritical marks and symbols like stars, crosses, or arrows. To do this, you'll need to use the “Hexadecimal Character References” found in the HTML specification. This will give you a specific code for each symbol which can then be used within an HTML document or web page. For example, if you need to insert a Dollar symbol on your website, you can use the code ‘$’ which will produce the desired result. With these methods in hand, anyone should be able to accurately represent any type of special character on their webpage.
What special characters are not allowed in passwords?
When creating passwords, using special characters can be a great way to make them unique and more secure.

For example, certain punctuation marks such as semi-colons or brackets should generally be avoided since these can be used by hackers to break into an account. In addition, spaces, tabs, and extra line breaks should also be excluded from passwords since they may cause authentication problems on some systems. While it is tempting to add a variety of special characters to make passwords secure, users should always make sure that these symbols are accepted by their services prior to implementation.
Which special characters are not allowed in SQL?
When using SQL, special characters can cause a variety of issues, and some are not allowed at all. The primary character that must be avoided is the single quote (‘). This character has a special meaning in SQL and using it can lead to incorrect query results. Additionally, many databases will also reject any other kind of quotation mark, including double quotes (“). Beyond this, most databases allow for an unlimited amount of Unicode characters in a query, with the exception of control characters such as linefeeds or null bytes. By avoiding certain characters and limiting queries to only those that are supported by the system you’re working with, you’ll be able to ensure all queries run smoothly and efficiently.
