Subject [jira] [Created] (CSV-58) Unicode escapes are lost if escape character is backslash
Date Wed, 14 Mar 2012 15:39:01 GMT
Unicode escapes are lost if escape character is backslash
---------------------------------------------------------

                 Key: CSV-58
                 URL: https://issues.apache.org/jira/browse/CSV-58
             Project: Commons CSV
          Issue Type: Bug
            Reporter: Sebb


The current escape parsing converts <esc><char> to plain <char> if the <char>
is not one of the special characters to be escaped.

This can affect unicode escapes if the <esc> character is backslash.

One way round this is to specifically check for <char> == 'u', but it seems wrong to
only do this for 'u'.

Another solution would be to leave <esc><char> as is unless the <char> is
one of the special characters.

There are several possible ways to treat unrecognised escapes:
- treat it as if the escape char had not been present (current behaviour)
- leave the escape char as is
- throw an exception
