From 7a18df8aab1638622ab93fd3203930399c680544 Mon Sep 17 00:00:00 2001 From: Gabriel Schneider Date: Tue, 29 Sep 2026 09:46:55 -0300 Subject: A tag write refuses NUL and the other control characters; a Dump that fails says so A NUL written into a tag went into the dump, which the host then could not write, and Dump said nothing: a success that wrote nothing. Tag writes, the workspace's, a column's and a pane's, refuse control characters but tab and newline, DEL, C1 and bytes not UTF-8, EINVAL; and Dump reports any failure of its own instead of swallowing it.
