The question of whether or not to use accented letters is based on the verbally expressed concern that search engines are unable to manage these correctly. For example, transfers of characters between different software systems handling bibliometric data by people or robots can sometimes convert accented characters to incorrectly coded character sequences. You can safely use 
Toru\'n
 in the LaTeX address for astronomy peer-reviewed journal articles, since this is handled well by standard fonts and conversions between codings; but it's better to use 
Torun
 in cases where, for example, you're worried that a web form will not be able to handle it. Using 
Grudziądzka
 instead of 
Grudziadzka
 is more risky and not recommended.
Post offices in Toruń in principle prefer the international standard of having a postcode associated with each post office, but the postcode tradition in Toruń is to pretend that everywhere in Toruń uses the central post office at 87-100.
