add link to taghistory.raifer.tech

[Klumbumbus]

Since taghistory now supports permalinks it would be nice if there would be a link below the taginfo link in the context menu of the Tags/Membership panel.

For a simple tag the link is e.g. ​https://taghistory.raifer.tech/#***/playground/swing

The data at taghistory.raifer.tech seems out-dated. There seems to be no new data since end of 2018?
Or maybe data was not collected for quite a while? One has to zoom out when a well known tag is checked.
​https://taghistory.raifer.tech/#***/landuse/farmland

It seems that tags which contain : cause problems, try e.g. addr:city=Bassum

Link that works:
​https://taghistory.raifer.tech/#***/addr:city/Bassum

Generated by JOSM:
​https://taghistory.raifer.tech/#***/addr%3Acity/Bassum

Not sure if this has to be fixed in JOSM or on the server side?

Yes, there was no data update for a longer time, but the dashed line ends always at the current real tag count.

Yes, I understood that after zooming out. On my machine, the link to landuse=farmland shows this result. Maybe there is an option to show the full curve?

I wanted to create an issue for that for a longer time. Now I did: ​https://github.com/tyrasd/taghistory/issues/30

":" is a reserved character, but that does not necessarily mean it must be encoded.

Anyway also
​https://taghistory.raifer.tech/#***/addr:municipality=København (which is generated by the server itself, but encoded by the browser)
does not work, so I'd say the server must be fixed to use and accept proper encoding for the permalink.

That's no fix, but a workaround. UTF-8 should not be transfered via URL unencoded, see previous comment.

In RFC 3986, I could not find anything forbidding : in the fragment part. Some related quotations:

​https://tools.ietf.org/html/rfc3986#section-2.2

reserved = gen-delims / sub-delims
gen-delims = ":" / "/" / "?" / "#" / "[" / "]" / "@"
sub-delims = "!" / "$" / "&" / "'" / "(" / ")" / "*" / "+" / "," / ";" / "="
These characters are called "reserved" because they may (or may not) be defined as delimiters by the generic syntax.

​https://tools.ietf.org/html/rfc3986#section-3.5

The characters slash ("/") and question mark ("?") are allowed to represent data within the fragment identifier.

I do not plan to do more research, considering that the use-case is not critical at all within JOSM.
