Re^2: Problem upgrading XML::Fast from 0.11 to 0.17

Hi,

It is the parser's job to handle decoding.

To do so, the parser needs to know the encoding of the XML.

The XML declaration (<?xml version="1.0" encoding="ISO-8859-1"?>) does provide that information for the parser.

$xml =~ s/^(?:.*\n)//;    # remove first line - the encoding line

By removing the XML declaration the Parser seems to guess the (wrong) source encoding. uses the default encoding.*

With XML declaration your code seems to work correctly. Please notice that XML::Fast upgrades the data to utf8. But now in the correct manner.

There's no guessing involved. If there's no encoding specified, then it must be UTF-8 to be valid XML.

See my reply to ikegami. I was opening the file with ISO-8859-1 and removing the XML encoding line because of previous bugs in XML::Fast.
