I cannot get the handwriting input to recognize this character, no matter how clearly I write it. I've double checked the stroke order in Pleco and verified it at YellowBridge Dictionary Are other people having issues with this one character?
Just tested in IOS. I was about to suggest that perhaps your stroke order is incorrect, but I just drew it as 夕，罒，口 (i.e. backwards) and Pleco picked it right up.
Can you enable the "very rare" setting on your phone to see if that makes a difference? Both Shun and I have it enabled and that's the only major difference in our settings from yours.
(On the other hand, 千, I have to draw correctly (left to right for the top stroke) or Pleco will not find it for me - I discovered that the hard way when I was first learning writing. It took me over 30 minutes to figure it out.. doh!)
啰 isn't part of GB or Big5 and so it's not covered by our basic free handwriting recognizer on Android - if you try the demo of our "Enhanced Handwriting Recognizer" in "Add-ons" (the same as the paid recognizer our iOS users are showing you) it should come right up in that.
The free, included handwriting recognizer in Android is somewhat limited. May well be that this character is part of the extended range of characters that's only supported by the paid handwriting recognizer. (Mike was 20 seconds before me.)
Thanks, I've purchased the add-on and indeed 啰 easily shows up now. In fact it's the character on the screenshot promoting the add-on! Middle State Tennessee University 啰 isn't in the top 10,000 frequent characters. So it makes sense that it isn't part of your basic package.
