Characters in activity names are not properly displayed

[eifelkiwi]

UTF characters (ä ö ü, but also emojis) in activity names are displayed in ISO 8859-1 (Latin-1) encoding on the webpage.

Additionally, some emojis (I could not reproduce which, but manually deleting all solved the problem) cause the script to throw an error (charmap undefinded)

Edit: those compound emojis cause a big problem, namely an undefined char 0x8f (which is not assigned). After this error occurs, I manually changed the csv, but had to clear the whole cache for the script to run through.

Eidt2: this seems to be a csv-parser thing only. Activities directly imported from Strava having emojis and umlauts are displayed correctly.
