PlantUML arrows

[wanno-drijfhout]

PlantUml defines a textual notation for a lot of diagrams. Arrow specifications like <-- and <- work really nicely with FiraCode. However, there's also specifications like <. and <.. (and of course .> and ..>) which represent dotted arrow lines. Or <--> etc. It would be amazing if Fira could also provide ligatures for those symbols.

Hi! I have a feeling those might conflict with math expressions in other languages:

x<.5
1.>x

Adding <--> shold be no problem. If you provide the full list I might implement some that would not interfere with other progamming languages

Hi! Thanks. I looked it up. The definitions seemed a bit scattered in this PDF but I think I found the most important ones.

• page 4
• page 31
• page 35

These pages list the examples and the corresponding graphics far better than I could reproduce here on GitHub, so I hope this is sufficient :-).
