Unlike PCs that present nightmares for Gīkūyū writers, Android inadvertently solved the keyboard constraints that the typical PC presents. The two letters ī and ū in Gīkūyū require a tilde (~) above the letter. The Android keyboard (am using 5.1) offers a way out if you can tolerate the bar instead of tilde. To get ū, press the letter u and hold for a second. You will see the following letters displayed from which you can chose: ū ü ù û ú In a similar way, you can select i and press the key for a second to get ì ï ī î í from which you can chose the desired letter. If you want upper case letters, press the shift button first↑. Hence you can get Ū and Ī. Cheers as you gleefully enjoy your vernacular. Above everything, the Messiah is coming soon . Prepare well
