XMLSyntaxError:Input is not proper UTF-8, indicate encoding,Odoo

Question

I am creating a module on odoo local(offline). To create it, it requires Model(in python) and View(in Xml). The module will then be installed, but an error occurred after creating the view.

This is the view.xml

<openerp>
<data> 
<record id="view_form_todo_task_inherited" model="ir.ui.view">
   <field name="name">Todo Task form – User extension</field>
   <field name="model">todo.task</field>
   <field name="inherit_id" ref="todo_app.view_form_todo_task"/>
   <field name="arch" type="xml">
      <field name="name" position="after">
         <field name="user_id" />
      </field>
      <field name="is_done" position="before">
         <field name="date_deadline" />
      </field>
      <field name="name" position="attributes">
         <attribute name="string">I have to...<attribute/>
      </field>
   </field>
</record>
</data>
</openerp>`

in creating the view it is important to make it inside <data> that is inside <openerp> otherwise it wont work.

When trying to install the module(which also will compile the codes), an error occurred and it indicates that there is something wrong with the view.xml file. It says

XMLSyntaxError: Input is not proper UTF-8, indicate encoding ! Bytes: 0x96 0x20 0x55 0x73, line 4, column 28

here is the traceback

Answer 1

I reformatted your xml to better check it and I noticed two things: 1. the data tag was missing 2. there where two "'" characters at the beginning and at the end of your xml. Because your trace says "Input is not proper UTF-8" it occurs to me that the problem could be given by this very same character.

Check in yor source file if they are there as well and remove them, then add the data tag as below.

<?xml version="1.0" encoding="utf-8"?>
<openerp>
<data> 
<record id="view_form_todo_task_inherited" model="ir.ui.view">
   <field name="name">Todo Task form – User extension</field>
   <field name="model">todo.task</field>
   <field name="inherit_id" ref="todo_app.view_form_todo_task"/>
   <field name="arch" type="xml">
      <data>
         <field name="name" position="after">
            <field name="user_id" />
         </field>
         <field name="is_done" position="before">
            <field name="date_deadline" />
         </field>
         <field name="name" position="attributes">
            <attribute name="string">I have to...</attribute>
         </field>
      </data>
   </field>
</record>
</data>
</openerp>
