hxunent(1) replace HTML predefined character entities by UTF-8

SYNOPSIS

hxunent [ -b ] [ -f ] [ file ]

DESCRIPTION

The hxunent command reads the file (or standard input) and copies it to standard output with &-entities by their equivalent character (encoded as UTF-8). E.g., &quot; is replaced by " and &lt; is replaced by <.

OPTIONS

The following options are supported:
-b
The five builtin entities of XML (&lt; &gt; &quot; &apos; &amp;) are not replaced but copied unchanged. This is necessary if the output has to be valid XML or SGML.
-f
This option changes how unknown entities or lone ampersands are handled. Normally they are copied unchanged, but this option tries to "fix" them by replacing ampersands by &amp;. Often such stray ampersands are the result of copy and paste of URLs into a document and then this option indeed fixes them and makes the document valid.

DIAGNOSTICS

The program's exit value is 0 if all went well, otherwise:
1
The input couldn't be read (file not found, file not readable...)
2
Wrong command line arguments.

BUGS

The program assumes entities are as defined by HTML. It doesn't read a document's DTD to find the actual definitions in use in a document. With -f, it will even remove all entities that are not HTML entities.
