I had a gig as a software developer at a company that tried to organize its software development with... the most horrid call center ticketing system I've ever seen.
The software was named "TANSS" (an acronym for "transaction action notification solution system" which... says a lot... in a certain way). It couldn't handle UTF-8 and the company had Asian customers, it placed the signature of a different company under each message sent to a customer and project management might as well have been non-existent (supposedly the crapper of a ticketing system had "projects" but it was just a super naive lining up of tasks without buffer times, burndown/velocity chart or anything).
The expensive p.o.s. was strong-armed into the company, probably because one of the company owners had a background in tech support crap where you're generally chasing billable minutes.
I don't know if it was unprofessional by me, but I quickly refused to interact with the whole thing and handed in my notice (and I had actually liked the company and my tasks up until that point). Even Jira, which many consider a highly unpleasant system to work with, felt lean, responsive and fun after that experience.
It's been over 6 years, but I can state with certainty, if I see that system in use anywhere, my respect is gone and whether customer or employer, they'll be a hot potato in my hands form that moment on :)
Lots of things are really bad with UTF-8. In Japan, lots of things still use SHIFT_JIS (or CP932 which expands on it), with some companies still using EUC_JP. I think MS application (Excel, etc.) all default to CP932 output instead of UTF-8.
