----
bool
isError() const;

== Description

Note that for an encoder, no input can cause an error; the possible errors result either from a call to the `convert` method after the `endConvert` method is called the first time, or from a call to the `endConvert` method after the `endConvert` method has returned successfully.

== Return Value

`true` if this encoder cannot achieve an acceptable result, and `false` otherwise
