Hi,

I’m very new to robofont so please forgive me if this question comes across silly.

I’m exporting some fonts from fontlab to UFO and I keep getting the following warning upon opening in robofont. (screen grab attached)

The ‘ tags I can only see from the output window, the groups and glyph names don’t seem to contain the ‘ tags, from what I can see. I can’t find where to remove the ‘ tags.

Have other people had this issue? How did they resolve it?

Best,
—Bobby

An easy way I’ve found is to go to the Finder, right-click or control-click on the UFO and select “Show Package Contents”. You will see a file called “groups.plist”. Open that in a plain text editor (like BBEdit or TextMate) and then search for ' (the apostrophe) and replace with “” (nothing). Save the file and reopen the UFO in RoboFont. If the UFO was already open in RoboFont, it will put up a message about the UFO having been changed outside of RoboFont, which you can confirm.

(Edit: Those should be “dumb” quotes above, not smart quotes. The forum software seems to be “fixing” them automatically.)

or easier, make a script that is removing all '
```
font = CurrentFont()

for groupName, items in font.groups.items():
    newItems = []
    for glyphName in items:
        if "'" in glyphName:
            glyphName = glyphName.replace("'", "")
        newItems.append(glyphName)
    
    if newItems != items:
        ## something changed
        font.groups[groupName] = newItems
```
and connect this script with event observer on fontDidOpen and it happens automatically.
see http://doc.robofont.com/api/mojo/mojo-events/

(RoboFont will never do this atomically cause one of the main principles is that the users should always be aware of what is happening with his/her font data)

Thank you both for your replies.

I tried both methods and they worked perfectly.

I couldn’t quite get the event observer to work properly as I’m pretty terrible at scripting.

Thanks again.

that is easy to :)
```
from mojo.events import addObserver


class RenameGroupsObserver(object):
    
    def __init__(self):
        
        addObserver(self, "checkGroupNames", "fontDidOpen")
    
    def checkGroupNames(self, info):
        print "checking group names for single quotes"
        font = info["font"]
        
        for groupName, items in font.groups.items():
            newItems = []
            for glyphName in items:
                if "'" in glyphName:
                    glyphName = glyphName.replace("'", "")
                newItems.append(glyphName)
    
            if newItems != items:
                ## something changed
                font.groups[groupName] = newItems
        print "done checking group names"


RenameGroupsObserver()
```
save this script in a file and add it in the preferences as a start up script and you never ever have to worry about single quotes in groups.
see http://doc.robofont.com/documentation/workspace/preferences/extensions/

Your font data will change and importing the UFO back in FL will change the groups behavior, off course

good luck
