Basic Knowledge

What is URL Encoding

URL encoding is the conversion of characters that cannot be written directly in URLs, such as Japanese characters and symbols, into percent-prefixed hexadecimal notation like "%E3%81%82". It is also called percent encoding. The long strings of % symbols you see when sharing Japanese URLs are an example of this.

Difference Between "+" and "%20" for Spaces

When encoding spaces, there are two methods: "+", which originates from the old convention of form submission, and "%20", which can be used in URLs generally. If you mistake which encoding method was used, discrepancies can occur in the decoding result, such as a "+" remaining or disappearing.
