Encoding problems in bio
Bios which contain (certain?) non-ASCII characters (only "ü"?) get scrambled.

Example: https://nitter.net/lu_eder -- "fünffachen" gets replaced by `f�<a href="/search?q=%23nffachen">�nffachen</a>` (note also the generated link that is not existing in the original bio).

Other example: https://nitter.net/PatzigProf -- "darüber" gets replaced by `dar�<a href="/search?q=%23ber">�ber</a>`
