I was using JQuery Autocomplete as a combobox and your needs work well with me and you can review the following code may be help you :
(function( $ ) {
$.widget( "ui.combobox", {
_create: function() {
var input,
self = this,
select = this.element.hide(),
selected = select.children( ":selected" ),
value = selected.val() ? selected.text() : "",
wrapper = $( "<span>" )
.addClass( "ui-combobox" )
.insertAfter( select );
input = $( "<input>" )
.appendTo( wrapper )
.val( value )
.addClass( "ui-state-default" )
.autocomplete({
delay: 0,
minLength: 0,
source: function( request, response ) {
var matcher = new RegExp( $.ui.autocomplete.escapeRegex(request.term), "i" );
response( select.children( "option" ).map(function() {
var text = $( this ).text();
if ( this.value && ( !request.term || matcher.test(text) ) )
return {
label: text.replace(
new RegExp(
"(?![^&;]+;)(?!<[^<>]*)(" +
$.ui.autocomplete.escapeRegex(request.term) +
")(?![^<>]*>)(?![^&;]+;)", "gi"
), "<strong>$1</strong>" ),
value: text,
option: this
};
}) );
},
select: function( event, ui ) {
ui.item.option.selected = true;
self._trigger( "selected", event, {
item: ui.item.option
});
},
change: function( event, ui ) {
if ( !ui.item ) {
var matcher = new RegExp( "^" + $.ui.autocomplete.escapeRegex( $(this).val() ) + "$", "i" ),
valid = false;
select.children( "option" ).each(function() {
if ( $( this ).text().match( matcher ) ) {
this.selected = valid = true;
return false;
}
});
if ( !valid ) {
// remove invalid value, as it didn't match anything
$( this ).val( "" );
select.val( "" );
input.data( "autocomplete" ).term = "";
return false;
}
}
}
})
.addClass( "ui-widget ui-widget-content ui-corner-left" );
input.data( "autocomplete" )._renderItem = function( ul, item ) {
return $( "<li></li>" )
.data( "item.autocomplete", item )
.append( "<a>" + item.label + "</a>" )
.appendTo( ul );
};
$( "<a>" )
.attr( "tabIndex", -1 )
.attr( "title", "Show All Items" )
.appendTo( wrapper )
.button({
icons: {
primary: "ui-icon-triangle-1-s"
},
text: false
})
.removeClass( "ui-corner-all" )
.addClass( "ui-corner-right ui-button-icon" )
.click(function() {
// close if already visible
if ( input.autocomplete( "widget" ).is( ":visible" ) ) {
input.autocomplete( "close" );
return;
}
// work around a bug (likely same cause as #5265)
$( this ).blur();
// pass empty string as value to search for, displaying all results
input.autocomplete( "search", "" );
input.focus();
});
}
});
})( jQuery );
and I think your needs in the following part but I don't know how to use that in your code :
source: function( request, response ) {
var matcher = new RegExp( $.ui.autocomplete.escapeRegex(request.term), "i" );
response( select.children( "option" ).map(function() {
var text = $( this ).text();
if ( this.value && ( !request.term || matcher.test(text) ) )
return {
label: text.replace(
new RegExp(
"(?![^&;]+;)(?!<[^<>]*)(" +
$.ui.autocomplete.escapeRegex(request.term) +
")(?![^<>]*>)(?![^&;]+;)", "gi"
), "<strong>$1</strong>" ),
value: text,
option: this
};
}) );
},

You can try something like this, based on code from jQueryUI: how can I custom-format the Autocomplete plug-in results?
function monkeyPatchAutocomplete() {
$.ui.autocomplete.prototype._renderItem = function (ul, item) {
var matchstring = [];
$.each(this.term.split(""), function(index, c){
matchstring.push("^"+c+"|\b"+c);
});
var output = item.label.replace(new RegExp("(" + matchstring.join("|") + ")", "gi"), '<span class="ui-menu-item-highlight">$1</span>');
return $("<li>")
.append($("<a>").html(output))
.appendTo(ul);
};
}
$(function () {
monkeyPatchAutocomplete();
});
May or may not work. The idea is to get a Regex string like ^G|\bG for each character. I'm sure this misses quite a few cases, so keep working on it.
Edit: working jFiddle. http://jsfiddle.net/9MC5M/ Like the code above but with a few bug fixes. The search is deliberatly broken, it just returns all items to showcase the highlighting.
