Steve --- You don't have to use the unicode itself - when you can cut/paste the actual character you want... so the change node just has the actual arrows in it. --- Actually "←" is an unicode string. If you want to use hex code 2190, you can use "\u2190" as a JSONata expression in change node. ```auto [{"id":"21b42045.65ad3","type":"tab","label":"Flow 1","disabled":false,"info":""},{"id":"6d1adb8e.557194","type":"ui_text","z":"21b42045.65ad3","group":"6b1cbf30.904d2","order":0,"width":0,"height":0,"name":"","label":"text","format":"{{msg.payload}}","layout":"row-spread","x":610,"y":220,"wires":[]},{"id":"3c8edd5b.5f2932","type":"change","z":"21b42045.65ad3","name":"←","rules":[{"t":"set","p":"payload","pt":"msg","to":"\"\\u2190\"","tot":"jsonata"}],"action":"","property":"","from":"","to":"","reg":false,"x":430,"y":140,"wires":[["6d1adb8e.557194"]]},{"id":"3986450a.2131aa","type":"change","z":"21b42045.65ad3","name":"↑","rules":[{"t":"set","p":"payload","pt":"msg","to":"\"\\u2191\"","tot":"jsonata"}],"action":"","property":"","from":"","to":"","reg":false,"x":430,"y":200,"wires":[["6d1adb8e.557194"]]},{"id":"10e1e202.ae148e","type":"change","z":"21b42045.65ad3","name":"→","rules":[{"t":"set","p":"payload","pt":"msg","to":"\"\\u2192\"","tot":"jsonata"}],"action":"","property":"","from":"","to":"","reg":false,"x":430,"y":260,"wires":[["6d1adb8e.557194"]]},{"id":"dc27a935.8c2978","type":"change","z":"21b42045.65ad3","name":"↓","rules":[{"t":"set","p":"payload","pt":"msg","to":"\"\\u2193\"","tot":"jsonata"}],"action":"","property":"","from":"","to":"","reg":false,"x":430,"y":320,"wires":[["6d1adb8e.557194"]]},{"id":"5adbc5ce.f4cb3c","type":"inject","z":"21b42045.65ad3","name":"","topic":"","payload":"","payloadType":"date","repeat":"","crontab":"","once":false,"onceDelay":0.1,"x":160,"y":140,"wires":[["3c8edd5b.5f2932"]]},{"id":"6a4e0eee.4ea52","type":"inject","z":"21b42045.65ad3","name":"","topic":"","payload":"","payloadType":"date","repeat":"","crontab":"","once":false,"onceDelay":0.1,"x":160,"y":200,"wires":[["3986450a.2131aa"]]},{"id":"4aad6473.22409c","type":"inject","z":"21b42045.65ad3","name":"","topic":"","payload":"","payloadType":"date","repeat":"","crontab":"","once":false,"onceDelay":0.1,"x":160,"y":260,"wires":[["10e1e202.ae148e"]]},{"id":"ee6e6bc.2e37798","type":"inject","z":"21b42045.65ad3","name":"","topic":"","payload":"","payloadType":"date","repeat":"","crontab":"","once":false,"onceDelay":0.1,"x":160,"y":320,"wires":[["dc27a935.8c2978"]]},{"id":"3ede91ea.05466e","type":"function","z":"21b42045.65ad3","name":"loop","func":"function loop(n) {\n var pos = n % 4;\n var msgs = [];\n for(var i = 0; i < n; i++) {\n msgs.push((i == pos) ? {payload:\"\"} : null);\n }\n node.send(msgs);\n if (n > 0) {\n setTimeout(function() {\n loop(n-1);\n }, 1000);\n }\n}\nloop(10);","outputs":4,"noerr":0,"x":290,"y":400,"wires":[["3c8edd5b.5f2932"],["3986450a.2131aa"],["10e1e202.ae148e"],["dc27a935.8c2978"]]},{"id":"17dfe88c.c2b407","type":"inject","z":"21b42045.65ad3","name":"","topic":"","payload":"","payloadType":"date","repeat":"","crontab":"","once":false,"onceDelay":0.1,"x":160,"y":400,"wires":[["3ede91ea.05466e"]]},{"id":"6b1cbf30.904d2","type":"ui_group","z":"","name":"Default","tab":"29a51209.1cbfde","disp":true,"width":"6","collapse":false},{"id":"29a51209.1cbfde","type":"ui_tab","z":"","name":"Home","icon":"dashboard","disabled":false,"hidden":false}] ``` --- This topic was automatically closed 30 days after the last reply.
