  "message": "[gdb/cli] Don\u0027t emit emojis in MI\n\nPR mi/34501 reports the following:\n...\n$ gdb -q \\\n    -ex \u0027set charset UTF-8\u0027 \\\n    -ex \u0027interpreter-exec mi2 \"-break-insert -f foo\u0027 \\\n    -ex quit\n\u0026\"�\\235\\214�\\217 No symbol table is loaded.  Use the \\\"file\\\" command.\\n\"\n  ...\n$\n...\n\nThe output is a bit odd, but that gets better if we use\n\u0027set print sevenbit-strings on\u0027:\n...\n\u0026\"\\342\\235\\214\\357\\270\\217 No symbol table is loaded.  Use the \\\"file\\\" command.\\n\"\n...\n\nThe output we see there is the error emoji:\n...\n$ gdb\n(gdb) b foo\n❌️ No symbol table is loaded.  Use the \"file\" command.\n...\n\nMore specifically, two utf-8 encoded unicode characters:\n- Cross Mark [1]: 0xE2 0x9D 0x8C\n- Variation Selector-16 (VS16) [2]: 0xEF 0xB8 0x8F\n\nNow the question: is GDB doing something wrong?\n\nI think we probably should encode unicode characters in MI error strings as\noctal escapes, independent of the sevenbit-strings setting.  This patch does\nnot address this part.\n\nThen there\u0027s the question whether we should emit emojis in MI error strings in\nthe first place [3].  In principle they\u0027re unicode characters encoded in UTF-8,\nand we can expect other such unicode characters in translated error strings.\n\nBut, given that MI has can_emit_style_escape () \u003d\u003d false, and already filters\nout ANSI escape sequences, I think it\u0027s reasonable to also disable emojis.\n\nAs for implementation, I introduced a function emoji_allowed alongside\ncan_emit_style_escape, which defaults to the value of can_emit_style_escape.\n\nTested on x86_64-linux.\n\nApproved-By: Tom Tromey \u003ctom@tromey.com\u003e\n\nBug: https://sourceware.org/bugzilla/show_bug.cgi?id\u003d34501\n\n[1] https://www.compart.com/en/unicode/U+274C\n[2] https://www.compart.com/en/unicode/U+FE0F\n[3] https://sourceware.org/bugzilla/show_bug.cgi?id\u003d33920#c1\n",
