xhtml Mobile Profile 1.2 dont work

For months the page in http://wcs.emprear.com/accesso_wcs.php pass the validator as XHTML Mobile Profile 1.2 without problems.
Now, this is the result:

#  Error  (http://www.openmobilealliance.org/tech/DTD/xhtmlmp12-form-1.mod) Line 18, Column 46: Input is not proper UTF-8, indicate encoding ! Bytes: 0x92 0x53 0x20 0x52
OR ITS AFFILIATES REGARDING ANY OF THE IPR�S REPRESENTED ON THE OMA
# Error (http://www.openmobilealliance.org/tech/DTD/xhtmlmp12-form-1.mod) Line 69, Column 17: conditional section INCLUDE or IGNORE keyword expected
<![%form.element;[
# Error (http://www.openmobilealliance.org/tech/DTD/xhtmlmp12-form-1.mod) Line 73, Column 39: xmlParseElementDecl: 'EMPTY', 'ANY' or '(' expected
<!ELEMENT %form.qname;  %form.content; >
# Error (http://www.openmobilealliance.org/tech/DTD/xhtmlmp12-form-1.mod) Line 73, Column 39: Content error in the external subset
<!ELEMENT %form.qname;  %form.content; >


I know, the recomended Doctype for mobile devices is XHTML Basic. But my question is Why Xhtml MP 1.2 givme these errors?
Is possible the xhtmlmp12-form-1.mod is corrupted? Or maybe The W3C Would have to remove from the validator the xhtml mp 1.2 the Doctype

Thanks
