 修学旅行！みゆき、京都でどん底ハッピー！？/ 'School Excursion! Miyuki's Least Happy in Kyoto!?'

I'll break it down the best I can.

京都-で-どん底-ハッピー

京都 / Kyoto - The location.

で / De - It's indicating a location, or time of action.

どん底 / Donzoko - Very bottom.

ハッピー / Happi - Exactly as that. The English word 'happy' with a Japanese pronunciation.

So, from what we gathered, the subs brought to you by the subbers you're watching, ended up attaching very bottom to ' Kyoto' , creating a title that makes little sense in context to the episode. Donzoko happi could also be interpreted as rock bottom happiness. XD

口 - It's an unknown number, from what I gathered. A blank number. So using '#' works as intended.

Also, no problem! Happy to help! ^_^ You work at your own pace.
