title: Where is my invalid character?
body: <p><strong>Every time I want to create a table in sql developer:</strong></p>
  
  <pre><code>create table tabelle(
  dgeh emp.sal%type)
  </code></pre>
  
  <p><strong>I get this error:</strong></p>
  
  <ol start="911">
  <li>00000 -  "invalid character"
  *Cause:    identifiers may not start with any ASCII character other than
         letters and numbers.  $#_ are also allowed after the first
         character.  Identifiers enclosed by doublequotes may contain
         any character other than a doublequote.  Alternative quotes
         (q'#...#') cannot use spaces, tabs, or carriage returns as
         delimiters.  For all other contexts, consult the SQL Language
         Reference Manual.
  *Action:</li>
  </ol>
  
  <p><strong>It's driving my crazy! Where is my invalid character? Thanks in advance!</strong></p>
