As the title says, I love this and think it's great, but in words like "This" "The" "That" "Thou" "Them" "Those" "These" etc. the glyph used is the DH and not the TH glyph. However, words like "Thigh" "Through" "Thorough" "Thought" use the correct TH glyph.

I'm not knowledgeable of phonetics, so maybe that's right, but it's always sounded the same to me when I and others I know speak.
