24553	Download object dialog does not ignore U+202E Unicode control character	ff5722	team	"==== What steps will reproduce the problem?
1. Paste text containing an unicode control character in the download object dialog ID field

{{{
1364346400‬
}}}

2. JOSM will say the Object ID is invalid

==== What is the expected result?
Either render the control character or trim it
==== What happens instead?
The ID visually looks valid but only after pasting in an advanced text editor the user can find why it was showns as invalid.
==== Please provide any additional information below. Attach a screenshot if possible.
As for why the U+202E character was included, I simply pasted a link from osm.org with Microsoft Edge, which became formatted as:

{{{
<a href=""https://www.openstreetmap.org/way/1364346400#map=16/25.58389/107.30486"" data-text-el=""text-only-link"" data-md-href=""https://www.openstreetmap.org/way/1364346400#map=16/25.58389/107.30486"" rel=""noopener noreferrer nofollow"">Way: ‪筑北高速‬ (‪1364346400‬) | OpenStreetMap</a>
}}}

It seems that basic escape characters like line endings are already trimmed, but I didn't test all the other 'rare' ones such as from this list https://unicode-explorer.com/b/2000
