[SalesForce] Encoding used when sending emails through singleemail method

When sending out a single email salesforce encodes the HTML body

As per doc :
https://www.salesforce.com/us/developer/docs/apexcode/Content/apex_classes_email_outbound_single.htm#apex_Messaging_SingleEmailMessage_setHtmlBody

setHtmlBody(String)

Optional. The HTML version of the email, specified by the sender. The
value is encoded according to the specification associated with the
organization. You must specify a value for setTemplateId, setHtmlBody,
or setPlainTextBody. Or, you can define both setHtmlBody and
setPlainTextBody

Where is this setting in a dev org to control the type of encoding?

Best Answer

Here is what is documented under the Implementation Considerations by Salesforce:

The API supports either full Unicode characters or ISO-8859-1 characters. The character set for your organization depends on the Salesforce instance your organization uses. If your organization logs into ssl.salesforce.com, then your encoding is ISO-8859-1. All other instances use UTF-8. You can determine the character set for your organization by calling describeGlobal() and inspecting the encoding value returned in the DescribeGlobalResult.
