Answers to Questions (FAQ)
What is a special character? (Definition)
A special character is a symbol that differs from the usual letters (a-z, A-Z) and numbers (0-9) (alphanumeric characters). Special characters encompass all other symbols, which may include punctuation marks, mathematical symbols, accents, etc.
Example: !, @, # are ASCII compatible special characters
Example: ☆, ♩, ∞ are Unicode special characters
What's wrong with special characters?
Some applications or systems may not support all special characters, resulting in display problems or error messages.
To overcome this problem, different forms of encoding have been created. Sometimes the encoding is preserved, but special characters are escaped characters (often \).
How to remove special characters?
To remove special characters, the user can enter their text in dCode and automatically remove non-ASCII characters or replace them with others.
Accents sometimes pose a problem, dCode also offers the removal of accents and diacritics.
