Browsers request pages from web servers by using a URL - the address of a webpage. These URLs can only be sent over the Internet as ASCII characters. However, they will often contain non-ASCII characters, for example, space.
URL encoding converts the original URL to the correct format. When you add new web panels, you may choose URL encoding directly in a drop-down menu.
Conversion replaces unsafe characters with a percent (%) followed by 2 hexadecimal digits. For example, space becomes %20. Thus:
- Characters up to 0x7F (127) are passed along unmodified
- Characters from 0x7F to 0xFF are encoded
Conversion transforms all characters to UTF-8 and then prefixes each character's 1–3 byte hexadecimal value with % according to RFC 2279.
