  • I can't type Unicode into text widgets

    From Luc@21:1/5 to All on Wed Mar 29 17:03:03 2023
    In Linux, I can type any (or almost any) Unicode character into
    text editors such as Leafpad, Pluma and Vim by holding Ctrl+Shift+U
    and typing the Unicode code. For example, Ctrl+Shift+U+2013 makes —.

    Why doesn't that work in my Tcl/Tk text widgets?

    You probably have an incompatible encoding.
    Do this and see if things improve:

    % encoding system utf-8

    Interesting - it works here even from a plain tclsh shell on command
    line as well as in text widgets, etc. I tested with emojis from here: https://www.unicode.org/emoji/charts/emoji-list.html

    What OS and what version are you using?


    What happens when you copy/paste an emoji directly like from that site?

    Because it may be the way you are entering these characters. I can't
    type Ctrl+Shift+U+2013 on my keyboard as the modifier sequence breaks on
    the "U". Too many modifiers :-) Maybe check the text widget doc's to
    see how you are supposed to type it in.

    Because you have not implemented it for your text widgets.

    X does not provide a "unicode hex entry" subsystem. So handling entry
    of unicode via typing the hex code is left up to the individual
    applications to implement.

    Most of them use a gui toolkit (GTK or QT) and this keystroke is
    probably part of the library, so it comes along for free for the
    individual apps.

    Tk is its own 'gui library' and it does not build in a "enter hex of
    unicode code point" feature. So you have to add it on yourself.

    Luc, that being said, if you develop such a set of bindings for the
    Entry and Text widgets, you may want to consider packaging them up and submitting them to TkLib.

    Gerald, I am deeply honored by the enormous amount of confidence you deposit
    in me and my abilities and I am sad to disappoint you. I'm afraid I cannot undertake such task because I wouldn't even know where to start and I know
    I would never be able to finish it. Genuinely sorry.

    It does. It works! It works pretty well.

    Except that I added it to my text editor and now many - not all - of the
    key bindings won't work anymore. I will have to have a closer look into
    that code and see if I can figure out what is going on.

    Very handy! Thank you.

    Pasting from elsewhere works, although "emojis" usually refers to a
    relatively new bunch of Unicode characters that Tcl doesn't even support
    except for one package whose name I forget.

    Hmm, I added as well an oowidgets example for easier use to the oowidgets Wikipage at the very end.

    https://wiki.tcl-lang.org/page/oowidgets

    or here embedded into the oowidgets project the manual page:

    https://htmlpreview.github.io/?https://raw.githubusercontent.com/mittelmark/oowidgets/master/paul/txmixins.html

    Which keybindings did not work anymore?

    These bindings don't work anymore while all others still work:

    bind $::w <Control-KeyRelease-f> {p.searchreplace}
    bind $::w <Alt_L><j> {p.gui6.switchtop}
    bind $::w <Alt_L><q> {exit 0}


    I've read that script many times and I can't really understand
    how it is supposed to work so I can't find out why some bindings
    won't work anymore.

    There is now an update from BEO in the wiki which says it does not interfere with other bindings:

    Could you try this out?

    you might try replacing these bindings:

    bind $::w <Alt_L><j> {p.gui6.switchtop}
    bind $::w <Alt_L><q> {exit 0}

    with

    bind $::w <Alt-j> {p.gui6.switchtop}
    bind $::w <Alt-q> {exit 0}
