title: ascii function in oracle sql, for non-ascii value
body: <p>In Oracle SQL:</p>
  <p>When we pass any non-ascii characters to ascii function, it is returning some number. How we can interpret that number. If we have character set as AL32UTF8, why its not returning Unicode point for given character</p>
  <pre><code>select * from nls_database_parameters where parameter = 'NLS_CHARACTERSET';--AL32UTF8
  
  select ascii('Á') from dual;--50049
  </code></pre>
  <p>what is the meaning of this value 50049?  I was expecting 193</p>
