Add filterable output to template tags

Hello,

I would like to see an ability to change the output of template tags with filters.
For example, I have a hashcat called “Výfukové systémy” which translates to #Výfukovésystémy ..this won’t work on social media. So I had to add my custom transliteration function so the output is #Vyfukovesystemy ..but I would like to have a custom filter in my theme’s functions.php so I don’t have to modify the plugin on each update. Transliteration is not the only thing I would do with hashcats and hashtags, so filters would be very helpful.
It would make sense to have custom filter for each template tag on each social media (for example “sap_hashcat_facebook_filter”, “sap_hashcat_twitter_filter” etc…
