G'day taint,

piconv converts character encodings. Here's an example of ISO-8859-1 to UTF-8 and back again (using the copyright sign): 

$ piconv -f ISO-8859-1 -t utf8 -s '©'
©

$ piconv -t ISO-8859-1 -f utf8 -s '©'
©

piconv does not look for keys such as "charset" or "encoding" and attempt to change their values.

Also, all the characters in the string "iso-8859-1" are ASCII; their values are identical to the Unicode code points of the corresponding characters. Had that meta element contained non-ASCII characters, you would have seen some conversion. 

$ piconv -f ISO-8859-1 -t utf8 \
>     -s '<meta http-equiv="Content-Type" content="text/html; charset=
+iso-8859-1">'
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1
+">

$ piconv -f ISO-8859-1 -t utf8 \
>     -s '<meta name="registered sign" content="®">'
<meta name="registered sign" content="®">

To convert your HTML files, you'll need to run piconv and also change "iso-8859-1" references to "utf-8". Be aware that there are several places in which encodings might be specified: for instance, meta and script elements may contain a charset attribute and XHTML documents may include encoding attributes.
