おんな の ひと は むずかしい です か？
女 is the Kanji for おんな, and I know this one
人 is the Kanji for ひと, and I know this one as well
If I enter 女の人は むずかしい です か？ In "Write It Native" on my iPhone, the software responds by changing the font on むずか to red font indicating I did something wrong and then changes it to the Kanji 難 (which I don't know, yet) in black 'font' with rest of characters green.
If I enter either
1) おんな の ひと は むずかしい です か？
2) 女の人は 難しい です か？
then all is well.
Not sure if this is because I messed up or the software just compares what I typed to either of options 1 or 2 and since I entered a hybrid of the two the software assumed I messed up.
From my perspective I'd rather start using Kanji in sentences as I learn them rather than wait until I learn all Kanji, even if I don't convert everything to Kanji that could be. I think I can just click the "good" button and override the error but don't want to do that if I've really messed up. And not sure how this would impact my score on the Certification test or benchmark?
Appreciate your feedback.
