This is a different problem; if you want to
insert special characters using DOM you should
just place them in the string, and let DOMWriter
escape them, if the output encoding is unable to represent them.
For instance,

Please be aware that every time you mix
std::string and XMLCh and do conversions between
them by means of X() or XMLString::transcode you
are doing a very tricky operation that you must
fully understand in order to succeed.
In this case, you *must* be sure that 0xA5 is a
valid character in the encoding of the machine
where your software is running, or the conversion
from local code page to Unicode will either fail
or return something you didn't anticipate.
Usually, I suggest to work directly with Unicode
strings, at least you know that the numbers you
put in the strings have only one symbol associated.
Alberto
thank for you help.

The result of writeToString is a Unicode string;
XMLString::transcode tries to convert that
Unicode string into the local code page of your
Linux box. I guess your current local code page
is unable to represent the Unicode character 0xA5
(the yen symbol). If you really want to display
that Unicode string on your terminal, you should
change your code page to be latin-1 or its equivalents (e.g. ISO-8859-1)
