title: Hibernate hbm2ddl on hsqldb create table with default value varchar column : unexpected token
body: <p>I try to generate schema on hsqldb for unit tests, I get an issue when creating table with column default value. It says in documentation that the default value for varchar must be single quote. But it doesn't work when a had single quotes in my hbm file. Without quotes I get another error : <strong>unexpected token:Europe</strong> because of the "/" I think.</p>
  
  <pre><code>ERROR 20-07-2017 09:55:48   HHH000388: Unsuccessful: create table PUBLIC.COMPANY (ID_COMPANY varchar not null, DESCR_COMPANY varchar not null,  COMPANY_TIMEZONE varchar default 'Europe/Brussels', primary key (ID_COMPANY)) - org.hibernate.tool.hbm2ddl.SchemaUpdate.execute(SchemaUpdate.java:235)
  
  ERROR 20-07-2017 09:55:48   unexpected token: : - org.hibernate.tool.hbm2ddl.SchemaUpdate.execute(SchemaUpdate.java:236)
  </code></pre>
  
  <p><strong>update</strong> try to escape with / and without single cotes</p>

  <p>It's the same error than without cote, I try with single quotes and escaping change nothing.</p>
  
  <p>It looks that special words eg:'NONE', 'STANDBY', 'DAY' involve an error too.</p>
  
  <p><strong>update</strong> quotes + escaping</p>
