 A Format Character Sequence (conversion specifier) is always 2 characters starting with a ''%'' character. Therefore, any text in the <html><b><span style="color:blue">format <span style="color:green">string</b></html> which is not preceded by a ''%'' character will be placed into the returned <html><b><span style="color:green">string</b></html> as literal text, unchanged.  Conversion specifiers are case-sensitive. A Format Character Sequence (conversion specifier) is always 2 characters starting with a ''%'' character.
