I'm writing a C# program and I'm using a fixed-width font to display everything. Under this font, every Unicode character either occupies 1 character width or 2 character width. In the program, there is a feature that needs to determine a particular character occupies 1 character width or 2 character width. At first I use the regex [^\x00-\xFF] to solve the problem. If a character matches it, it occupies 1 character width, otherwise it's 2 character width. But later I found this is not correct. For example, these characters ┌─┬┐│├┼┤┴┘ don't fall in the range of [^\x00-\xFF] but they all just occupies 1 character width. I want to know in C# how to determine a specific character occupies 1 character width or 2 when using fixed-width font?
I'm also searching for the same question's answer... but I haven't found it. by the way, I finally write a library to get length of character (generate a range information which shows character length use Console.Write() and Console.CursorLeft, and then convert to C# code, when get character length, use binary search for higher speed)
