When ELinks runs in an X11 terminal emulator (e.g. xterm), or in GNU Screen, it tries to update the title of the window to match the title of the current document. To do this, ELinks sends an "OSC 1 ; Pt BEL" sequence to the terminal. Unfortunately, xterm expects the Pt string to be in the ISO-8859-1 charset, making it impossible to display e.g. Cyrillic characters. In xterm patch #210 (2006-03-12) however, there is a menu item and a resource that can make xterm take the Pt string in UTF-8 instead, allowing characters from all around the world. The downside is that ELinks apparently cannot ask xterm whether the setting is on or off; so add a terminal._template_.latin1_title option to ELinks and let the user edit that instead. Complete list of changes: - Add the terminal._template_.latin1_title option. But do not add that to the terminal options window because it's already rather crowded there. - In set_window_title(), take a new codepage argument. Use it to decode the title into Unicode characters, and remove only actual control characters. For example, CP437 has graphical characters in the 0x80...0x9F range, so don't remove those, even though ISO-8859-1 has control characters in the same range. Likewise, don't misinterpret single bytes of UTF-8 characters as control characters. - In set_window_title(), do not truncate the title to the width of the window. The font is likely to be different and proportional anyway. But do truncate before 1024 bytes, an xterm limit. - In struct itrm, add a title_codepage member to remember which charset the master said it was going to use in the terminal window title. Initialize title_codepage in handle_trm(), update it in dispatch_special() if the master sends the new request TERM_FN_TITLE_CODEPAGE, and use it in most set_window_title() calls; but not in the one that sets $TERM as the title, because that string was not received from the master and should consist of ASCII characters only. - In set_terminal_title(), convert the caller-provided title to ISO-8859-1 or UTF-8 if appropriate, and report the codepage to the slave with the new TERM_FN_TITLE_CODEPAGE request. The conversion can run out of memory, so return a success/error flag, rather than void. In display_window_title(), check this result and don't update caches on error. - Add a NEWS entry for all of this. |
