user60264: I noticed during a conversation with User ᴅᴀɴɪᴇʟッ under a post of mine that the last character ッ does not appear in the autocompletion when I start my comment with @ to ping them. Most probably this is because ッ doesn't come from a "standard" Roman script? I believe the pings are going through, but the best person to confirm or deny this would be ᴅᴀɴɪᴇʟッ.
One can test this by picking any comment by ᴅᴀɴɪᴇʟッ from their activity page to reply to. (Of course, there is no need to actually post a comment to test this, so I'm not inviting spam to rain down on them. I hope.)
Can the username autocomplete please be made to pick up all the characters?

user59761: Yes, the pings do come to me. It is pretty weird though, how the last character is left off when someone is trying to @ me (in a posts comments). Nonetheless, I do get the ping, so this ain't much of an issue.
This is especially weird because when I was talking with user @Makoto on MSE, the ッ is there. And when I'm in chat, and get pinged, it's there is well (here is an example conversation). Kinda weird for it to just not show up on A&M.
I do not participate on too many SE sites, and I've only noticed this on A&M. I do see the ッ on other Stack Exchange networks though.
I doubt this is from it being a special character,since every part of my username is.
