 Adafruit_SSD1306 (int8_t mosi_pin, int8_t sclk_pin, int8_t dc_pin, int8_t rst_pin, int8_t cs_pin)
 DEPRECATED constructor for SPI SSD1306 displays, using software (bitbang) SPI. Provided for older code to maintain compatibility with the current library. Screen size is determined by enabling one of the SSD1306_* size defines in Adafruit_SSD1306.h. New code should NOT use this.

But a TON of code has been written with the erroneous character indices. By default, the library uses the original 'wrong' behavior and old sketches will still work. Pass 'true' to this function to use correct CP437 character values in your code.
