LF, VT, FF and CR are considered whitespace, and also mandatory line breaks in the line breaking algorithm. FS, GS, RS and US are considered separators in the bi-directional algorithm." Thus if I encounter an HT control code in some UTF-8 file then I should process that code as whitespace. But a specific application may choose to use the HT control code for some other purpose.
