…tle support When creating an X11 window, only WM_NAME was set with type STRING (Latin-1), causing UTF-8 characters (e.g. em-dash in \"Zed — Settings\") to render as garbled bytes in taskbars and window previews. Fix: also set _NET_WM_NAME with UTF8_STRING during window creation, consistent with how set_title() already handles subsequent title updates. Fixes zed-industries#51871

Context
On Linux X11, the Settings window title was displayed as garbled text
("Zed â██ Settings") in taskbars and window previews due to incorrect
character encoding.
Root cause: During X11 window creation, only
WM_NAMEwas set withtype
STRING(Latin-1). The em-dash character (U+2014) in "Zed — Settings"is a multi-byte UTF-8 sequence (
0xE2 0x80 0x94), which Latin-1 cannotrepresent correctly.
Fix: Also set
_NET_WM_NAMEwith typeUTF8_STRINGduring windowcreation, consistent with how
set_title()already handles subsequenttitle updates.
Fixes #51871
Release Notes:
