This is an issue that I ran into when I first began modding. To provide context I'm making a mod in which I replace the Malians with Tibetans, let's say I wan't to change "Buildings are 15% cheaper" to "Monestaries are cheaper"

In the document, the entire string is;
120175 "Infantry civilization \n\n· Infantry armor research provides +1 additional pierce armor per research \n· Monasteries cost 100 wood. Standing monks generate gold.\n· Monasteries, Towers get +25% hp in Castle and +25% in Imperial \n\n<b>Unique Unit:<b> Dharmaphala (Mountable infantry)\n\n<b>Unique Techs:<b> Lamellar (Infantry get +1/+1 armor); Nirvana (Monks regain faith 75% faster)\n\n<b>Team Bonus:<b> Blacksmith research doubly faster"

However when I change this at ALL, even something as miniscule as changing one character (like 15% to 18%, just to test if it was a character limitation issue), when booting up the game with the text interface mod enabled, it will prompltly freeze and crash IF I click on the tech tree for the edited civ.

Yes, I use the modded-strings utf8, and yes it works fine otherwise with unit and technology names. However it is specifically the civ information, which is naturally vital to a mod for replacing a civ, that causes these problems. Any other insights on this would be appreciated
