Hi Shree, Thanks for your kindly response! It's very clear. Actually, I'm also curious about some languages whose "character" might be consist of multiple "glyphs" (not sure if I use correct English words to describle - sorry for my poor English in advance) . Your example also include this part. Thank you so much!
