Although it is known as URL-encoding it is, in fact, used more generally within the main Uniform Resource Identifier (URI) set, which includes both Uniform Resource Locator (URL) and Uniform Resource Name (URN). URL-encoding, also known as "percent-encoding", is a mechanism for encoding information in a Uniform Resource Identifier (URI). URL-encode your data without hassles or decode it into a human-readable format. search?q=`Abdu 'l-Bahá Java import java.io.Meet URL Decode and Encode, a simple online tool that does exactly what it says: decodes from URL-encoding as well as encodes into it quickly and easily. As the parenthesized expression containing hfd is only evaluated at definition time, there's no performance penalty from the use of toupper. The addition of toupper guarantees the case insensitivity required by RFC 3986 regardless of which version of J you are using. J8, in contrast, provides a lower case result from hfd. Note that an earlier implementation assumed the j6 implementation of hfd which where hexadecimal letters resulting from hfd were upper case. J does not have a native urldecode (until version 7 when the jhs ide addon includes a jurldecode). While the default is to decode parameters as UTF-8 (which is the W3C recommendation,) the characters may have been encoded in another encoding scheme, and this can be handled correctly.
