Special characters in fields being encrypted are converted when entity is updated

Hi,

We are using field encryption module to encrypt our users fields and a custom entity's fields.
now when the entity is being created via web form, the fields values are saved correctly. If there is a special character in field value the 'value' key is having exact value and 'safe value' key has the value with special char converted to HTML entities like '&amp'
the issue happens when I am updating just a date field of this entity via entity load and entity save() functions, this time the value gets the HTML converted values i.e. '&amp' and safe value gets '&amp' converted to &ampamp;
now in views the field values are showing incorrect.
When I unchecked the Encrypt option via field settings, no matter how many times I am updating any value of entity the 'value' key of field will always have the exact entered value I.e. no HTML conversion.
Please help.
