@pavsmith With such a small difference they will probably read it correctly, but this can be a problem with some dictionaries or input methods that rely on splitting characters into elements: 丨 and 丶 might be different elements.
E.g. while Cangjie inputs both 房 as HSYHS (/尸丄/𠃌), it would split ⻆ into NBG (乛⺆土) or NBQ(乛⺆扌), 直 into JBMM (十⺆一一) or JBUV (十⺆凵𠃊). Another example, 今, might be OIN (人丶乛) or OMN (人一乛). An input method only accepts one of these. Typing with wrong font can be painful.
@zmicier thank you. that is quite amazing! and there are regional variations! it must be quite an experience to learn it. my usual question, though: can left handers do it routinely? the shape of some of the pictograms look like they'd be tricky, kinda like having to write backwards.
