rg/en/jsr/detail?id=283">JSR-283 by converting the reserved characters (namely '*', '/', ':', '[', ']' and '|') to their unicode equivalent.
{@link #URL_ENCODER UrlEncoder} - an encoder and decoder that is useful for converting text to be used within a URL, asdefined by Section 2.3 of RFC 2396. This encoder does encode many characters (including '`', '@', '#', '$', '^', '&', '{', '[', '}', ']', '|', ':', ';', '\', '"', '<', ',', '>', '?', '/', and ' '), while others are not encoded (including '-', '_', '.', '!', '~', '*', '\', ''', '(', and ')'). Note that only the '*' character is the only character reserved by JSR-283 that is not encoded by the URL encoder.
{@link #NO_OP_ENCODER NoOpEncoder} - an {@link TextEncoder encoder} implementation that does nothing.

This class simplifies working with paths and using a Path is often more efficient that processing and manipulating the equivalent String. This class can easily {@link #iterator() iterate} over the segments, returnthe {@link #size() number of segments}, {@link #compareTo(Path) compare} with other paths, {@link #resolve(Path) resolve}relative paths, return the {@link #getParent() ancestor (or parent)}, determine whether one path is an {@link #isAncestorOf(Path) ancestor} or {@link #isDescendantOf(Path) decendent} of another path, and{@link #getCommonAncestor(Path) finding a common ancestor}.
