I am using org.geotools version 2.7.0 and I am trying to get some shapefiles to GML 3.1.1. Sadly I got an exception:
java.lang.RuntimeException: Encode failed for _Feature. Cause: INVALID_CHARACTER_ERR: An invalid or illegal XML character is specified.

Maybe it's a space or an accented char (shape's attributes are full of accented chars) but I am very new to geotools and GIS, this error is completely blocking me. I can't find a way to specify a charset to read data from shape (by set up DataStore) or to write data into GML file (by set up Encoder). What am I missing?
update:
I am tryintrying to remove not allowed symbols from attributes and element names by using
StringBuilder sb = new StringBuilder();
if (!s.substring(0, 1).matches("[a-zA-Z_]"))
throw new IllegalArgumentException();
sb.append(s.substring(0, 1));
for (int i = 1; i < s.length(); i++) {
if (s.substring(i, i + 1).matches("[a-zA-Z0-9_.-]")) {
sb.append(s.substring(i, i + 1));
}
}
return sb.toString();
to sanitize shape feature attribute's values. Now attributes looks good but I am still getting the same exception. As I say
I am new to GIS and org.geotools, any hint is appreciated.
