[search] Fixed emoji.

The "information box" emoji U+2139 was converted to the letter "i" after
all simplifications. As a result, every token that started with
this letter had the tourism-information category as its synonym.

This was the only case where a normalized and simplified emoji
resulted in a pure ASCII string.
