## Using special characters in an XML file {#mid-server-reserved-characters__section_mtl_kbk_chb}
The XML specification defines five predefined entities that represent special characters,
and requires that all XML processors honor them. If these characters are used in a password,
you will experience unexpected results.
The following characters represent the five pre-defined entities:
* "
* \&
* '
* \<
* \>
{#mid-server-reserved-characters__ul_ntl_kbk_chb}
If you use the pre-defined entity characters in an XML file, such as the MID Server configuration file, you need to encode them. To encode pre-defined entities into an XML document:
* replace " with \"
* replace \& with \&
* replace ' with '
* replace \< with \<
* replace \> with \>
{#mid-server-reserved-characters__ul_otl_kbk_chb}
For example, to specify the password as test& in the MID Server
config.xml file:
