This template (context in that page ελληνιστική κοινή *ἀστέριον) directs to the γλωσσολογία page (not necessary in our case) and has a tooltip "αμάρτυρος υποθετικός τύπος (ή αντιγραμματικός)" (meaning "a non-attested form")

Currently it renders as: https://github.com/BoboTiG/ebook-reader-dict/blob/4db5a40cbda3ac85eed3bed3f0c9434c982e0fe1/wikidict/lang/el/__init__.py#L94

I guess, a better support would be to simply ignore the template. It is not useful to display a "*" in the text.

Just replace with a normal asterisk symbol (not big), it is standard to indicate such words, see https://linguistics.stackexchange.com/questions/338/meaning-of-star-asterisk-in-linguistics

Currently the output as I see it on GoldenDict using Stardict file is: {{*}}

A simple asterisk symbol is fine, yes 👍
