output_charset
The character set encoding identifier of the output document, such as iso-8859-1 or windows-1251. Some character sets must be converted before they can be used in, for example, email or PDF documents. If the default charset is one of them, this attribute will contain the name of the character set output will be converted to. You should normally leave this blank so a default value is used.
Default value
/lxml:data/lxml:server-instructions/lxml:client-charset
Valid values
Single quote character set value.
