All the native speakers of Japanese that I have consulted tell me that these kanji look odd, definitely non-standard. They have never seen "soto" or "uchi/KA" written this way in handwriting, and hardly ever in books.
My teacher told me that if any student wrote these kanji in the VL-Gothic way, they would be corrected. She also said that the way these characters appear in VL-Gothic (and other computer fonts) looks like the versions in the old "Kouki Jiten" Kanji dictionary, compiled in China in 1716.
Does anyone know of a computer kanji font that uses the standard form of these characters, the form that is used in printing books and is taught to students in Japan?
