+ *
+ * To keep synchronization between ATK offsets (unicode codepoints) and DOM
+ * offsets (UTF-16 code units), after translation from UTF-16 to UTF-8 we add a

+ * code units for only 1 unicode codepoint).
+ *
+ * BOMs (Byte Order Marks, U+FEFF, also known as ZERO WIDTH NO-BREAK SPACE, but

+ * files, but their occurrence within text (notably after cut&paste) is not
+ * uncommon, and are thus considered as non-text.
+ *
+ * Since the selection requested through ATK may not contain both surrogates
+ * at the ends of the selection, we need to fetch one UTF-16 code point more
+ * on both side, and get rid of it before returning the string to ATK. The
+ * ATKStringConverterHelper class maintains this, NewATKString should be used
+ * to call it properly.
+ *
+ * In the end,
+ * - if the start is between the high and low surrogates, the UTF-8 result
+ * includes a BOM from it but not the character
+ * - if the end is between the high and low surrogates, the UTF-8 result

+ STATE_FLOATING: No ATK equivalent. No known use case.
+ The nsIAccessible state is not currently supported.
+ STATE_MOVEABLE: No ATK equivalent. No known use case.
+ The nsIAccessible state is not currently supported.
+ STATE_SELFVOICING: No ATK equivalent -- the object has self-TTS.
+ The nsIAccessible state is not currently supported.
+ STATE_LINKED: The object is formatted as a hyperlink. Supported via ATK_ROLE_LINK.
+ STATE_EXTSELECTABLE: Indicates that an object extends its selection.
+ This is supported via STATE_MULTISELECTABLE.
+ STATE_PROTECTED: The object is a password-protected edit control.
+ Supported via ATK_ROLE_PASSWORD_TEXT
+ STATE_PINNED: The object is pinned, usually indicating it is fixed in

+The following ATK states are not supported:
+ ATK_STATE_ARMED: No clear use case, used briefly when button is activated
+ ATK_STATE_HAS_TOOLTIP: No clear use case, no IA2 equivalent
+ ATK_STATE_ICONIFIED: Mozilla does not have elements which are collapsable into icons
+ ATK_STATE_TRUNCATED: No clear use case. Indicates that an object's onscreen content is truncated,
