The error:

After inspecting game files, the actual tag data looks like this (in foa/tagsgdx3_ui.txt):
发动攻击时 tagRefreshSkillCondition07={%d0}% {^E}几率触发
While the EN tag is:
tagRefreshSkillCondition07={%d0}% {^E}Chance on Attack
This applys to all tagRefreshSkillCondition tags
So I assume this is a bug caused by placing unicode chars before the actual tag?
