When I installed Joplin about 2 months ago, I am pretty sure I was able to type "->" in markdown, and the rendered text was converted to "→". Now this does not work anymore, but I am not quite since when. I have the same plugins (that are included with Joplin) activated as before. Any idea why this happened?
I do believe I didn't install any fonts during this time, and I don't have selected a font selected in Joplin.
According to development tools, rendered text is using 'Avenir', 'Arial', sans-serif, not sure if if was the same before (since this seems to be the font selected by default).
Here I see the arrow appearing ONLY when I enter it in handwriting on my Samsung pen-enabled tablet.
In this very specific case it does work : I just hand-draw an arrow, the Samsung interpreter turns it into an arrow. And that arrow then appears on any other machine, Linux or Android.
In all other cases (keyboard typing, or any other Android machine, or on the computer) '->' remains '->'
So this means at least the 'nice arrows' are already handled on very Joplin instances, it's only a matter of entering the right character apparently... which is performed by my handwriting recognition on the tablet...
Since I never could remember the numbers I use these html codes:
Up arrow (↑): ↑
Down arrow (↓): ↓
Left arrow (←): ←
Double headed arrow (↔): ↔
Right arrow (→): →
Right arrow (↠): ↠
North east arrow (): North-East
Right arrow (⇒): ⇒
You probably got the patter with the different direction...
By the way, in joplin they look nicer than here
