INPUT:
Instead of string, each of these can be unicode in Python 2:
- ``character`` -- string. The single-line version of the symbol.
- ``top`` -- string. The top line of a multi-line symbol.
- ``extension`` -- string. The extension line of a multi-line symbol (will be repeated).
- ``bottom`` -- string. The bottom line of a multi-line symbol.
- ``middle`` -- optional string. The middle part, for example in curly braces. Will be used only once for the symbol, and only if its height is odd.
- ``middle_top`` -- optional string. The upper half of the 2-line middle part if the height of the symbol is even. Will be used only once for the symbol.
- ``middle_bottom`` -- optional string. The lower half of the 2-line middle part if the height of the symbol is even. Will be used only once for the symbol.
- ``top_2`` -- optional string. The upper half of a 2-line symbol.
- ``bottom_2`` -- optional string. The lower half of a 2-line symbol.
