So, I just hooked up an I2C LCD and tested a compile of Marlin 1.1.9 (using Arduino 1.8.5) - and the LCD is working with the "LCD_SAINSMART_I2C_2004" option enabled.
I did however already have the "Newliquidcrystal_135" LCD library installed.
This library you can find here: [bitbucket.org]
But back to getting the encoder to work........
