bug: simulator.json lists some strange fonts

For some devices the simulator.json has some "strange" fonts in some fontSets. For example: approachs50: in the "apac_tha" fonts:

        {
            "fontSet": "apac_tha",
            "fonts": [
                {
                    "filename": "bitstreamVeraSans 16",
                    "name": "xtiny"
                },
                {
                    "filename": "bitstreamVeraSans 16",
                    "name": "tiny"
                },
                {
                    "filename": "bitstreamVeraSans 16",
                    "name": "small"
                },
                {
                    "filename": "bitstreamVeraSans 21",
                    "name": "medium"
                },
                {
                    "filename": "bitstreamVeraSans 27",
                    "name": "large"
                },
                {
                    "filename": "FNT_006B465600_NUMBER_XSMALL",
                    "name": "numberMild"
                },
                {
                    "filename": "FNT_006B465600_NUMBER_SMALL",
                    "name": "numberMedium"
                },
                {
                    "filename": "FNT_006B465600_NUMBER_LARGE",
                    "name": "numberHot"
                },
                {
                    "filename": "FNT_006B465600_NUMBER_XLARGE",
                    "name": "numberThaiHot"
                },
                {
                    "filename": "bitstreamVeraSans 16",
                    "name": "glanceFont"
                },
                {
                    "filename": "bitstreamVeraSans 16",
                    "name": "glanceNumberFont"
                },
                {
                    "filename": "bitstreamVeraSans 16",
                    "name": "auxiliaryFont1"
                },
                {
                    "filename": "FNT_006B465600_NUMBER_MEDIUM",
                    "name": "simExtNumber1"
                }
            ]
        }

The fonts with capital filename can be found, but the bitstreamVeraSans fonts can't be found.
