What are special characters in text? +
Special characters are any characters that are not standard letters (a-z, A-Z) or numbers (0-9). This includes symbols like @, #, $, %, punctuation like commas and periods, brackets, emojis, and other non-alphanumeric characters. They often cause issues in databases, file names, URLs, and programming code.
Why would I need to remove special characters? +
You may need to remove special characters when cleaning data for a database, preparing text for CSV import, sanitizing user input, creating clean file names, processing text for NLP or machine learning, or cleaning scraped web content. Special characters can break SQL queries, corrupt files, and cause encoding errors.
Can I keep spaces and hyphens while removing other characters? +
Yes. By default this tool keeps spaces, hyphens, and underscores intact. You can toggle exactly which character types to remove using the checkboxes. Use the custom characters field to add or remove any specific characters you need to handle differently.
Does this tool remove emojis? +
Yes. The emoji removal option strips all Unicode emoji characters from your text using a comprehensive Unicode range pattern. This includes all common emojis, symbols, pictographs, and other Unicode special characters that are not standard Latin text.
