An interesting side effect of Japanese stroke order (at least with Japanese characters) is that character recognition for dictionary apps etc is based around stroke order. If you mess up the stroke order badly enough then it won't recognize the character at all.

I've noticed this pattern too. For example, try to draw the character 口 on the 'draw' functionality on jisho.com -- the correct stroke order is (cardinal directions for 3 strokes): 1. NW -> SW 2. NW -> NE -> SE 3. SW -> SE. If you try to do it any other way it will fail. If this is a problem for you (e.g. learning Japanese and don't know stroke orders and/or don't care to learn them exactly) -- the Google Translate handwriting input for Japanese does not have this behavior (or at least as much) and will effectively recognize your incredibly shittily reproduced kanji.

  Maybe those old dictionary software hold kanji as graphs internally and search as hierarchical trees. That would be far faster and more accurate than comparing 酒酉西 out of bitmaps as long as the user knows the order...

  ╷ ┌ ┌┐ 口

    the second stroke of 口 goes right from your first glyph ╷ to the third glyph ┌┐ said another way, your second glyph ┌ doesn't appear in the "correct stroke order" because the top+right sides of the 'mouth' are drawn in one stroke.

      I expect their list is for ordering, not individual stroke. If you only put ╷ and ┌┐ you could get to the second by starting at the bottom right. The alternative would be to list individual strokes e.g. ╷, ┐, ─. Or to use bolding but it's really hard for me to notice that┍┓is BOX DRAWINGS DOWN LIGHT AND RIGHT HEAVY followed by BOX DRAWINGS HEAVY DOWN AND LEFT. Plus it still doesn't really specify stroke order.

      ╷ Down ┌┐ Right, down 口 Right

  Because this is so ingrained in me from learning chinese, this is how i draw all my boxes as well when prototyping in the whiteboard. And same, you end up with that inverted acute trapezoid shape once you start going fast.
