Unicode 18.0.0

What is a Unicode control character?

A control code rather than an ordinary visible symbol. Code points: U+0007. Programs may interpret, ignore, escape or reject it. No fallback is suggested. Font coverage, shaping, and application acceptance were not tested, so those results are unknown.

What was checked

Control character

A control code rather than an ordinary visible symbol.

Programs may interpret, ignore, escape or reject it.

Use an explicit escaped representation when discussing a control code; do not paste it invisibly into untrusted contexts.

What this does not prove

No OS, font, browser, application, field policy or rendering engine was tested. Unicode validity and segmentation do not establish actual display or acceptance.
