Each list entry must have the format: "[target] [search] [search] .." (for example "a 𝒜 @ à") whereas each "search" (𝒜, @ and à) will be replaced by "target" (a) before Highlight matching takes place. This is intended to normalize lookalikes to a single character for easier matching. The original "search" characters can not be matched on. In other places, for example for display in chat, the original message will be used.
