When initializing the indicator label, no particular limit is
enforced for the length of “shortName”:

    /usr/share/gnome-shell/ui/status/keyboard.js:714

    const InputSource = new Lang.Class({
        Name: 'InputSource',

        _init: function(type, id, displayName, shortName, index) {
            this.type = type;
            this.id = id;
            this.displayName = displayName;
            this._shortName = shortName;
            this.index = index;

            this._menuItem = new LayoutMenuItem(this.displayName, this._shortName);
            this._menuItem.connect('activate', Lang.bind(this, this.activate));
            this._indicatorLabel = new St.Label({ text: this._shortName });

            this.properties = null;
        },
    [...]

But when updating the indicator label because of the property “InputMode”,
the text is ignored when it is longer then 2 characters:

    /usr/share/gnome-shell/ui/status/keyboard.js:714
    
    _buildPropSubMenu: function(menu, props) {
        if (!props)
            return;

        let radioGroup = [];
        let p;
        for (let i = 0; (p = props.get(i)) != null; ++i) {
            let prop = p;

            if (!prop.get_visible())
                continue;

            if (prop.get_key() == 'InputMode') {
                let text;
                if (prop.get_symbol)
                    text = prop.get_symbol().get_text();
                else
                    text = prop.get_label().get_text();

                if (text && text.length > 0 && text.length < 3)
                    this._currentSource.indicatorLabel.set_text(text);
            }
    [...]

This is a bit inconsistent.

ibus-typing-booster for example uses the symbol “en-GB” for British English
which is 5 characters long and displayed fine (ibus-typing-booster
does not use an “InputMode” property).

But the most recent version of ibus-table uses an “InputMode”
property and for the non-Chinese tables it sets the symbol
to  “'☑' + symbol” when the input method is active and
“'☐' + symbol” when the input method is in direct keyboard mode.
So this works only when “symbol” is no longer than 1 character.
But some tables have slightly longer symbols, e.g. translit has
the symbol “Ya” and translit-ua has the symbol “Yi”.

I think “☑Ya”/“☐Ya” is still reasonably short and should be allowed,
especially if such symbols are allowed during initialization.

So could the check “text.length < 3” be removed? Or at least a somewhat
longer value like “text.length < 6” be used?
