Tab Stops (HT)

Category: unicode · Tags: ECMA-48 Standard, VT100 · Specification ↗

HT (0x09) advances the cursor to the next tab stop. Default tab stops are at every 8th column. Terminals should support HTS (ESC H) to set custom tab stops and TBC (CSI 3 g) to clear them.
How this is tested: Send a tab character, verify cursor moves to column 8.
