-/**
- * String parser of popupCharacters attribute of Key.
- * The string is comma separated texts each of which represents one popup key.
- * Each popup key text is one of the following:
- * - A single letter (Letter)
- * - Label optionally followed by keyOutputText or code (keyLabel|keyOutputText).
- * - Icon followed by keyOutputText or code (@icon/icon_number|@integer/key_code)
- * Special character, comma ',' backslash '\', and bar '|' can be escaped by '\'
- * character.
- * Note that the character '@' and '\' are also parsed by XML parser and CSV parser as well.
- * See {@link KeyboardIconsSet} about icon_number.
