AS3: How to find source of embed fonts?

Question

I'm investigating huge legacy project, where many SWF assets are dynamically loaded. I guess designers used embedded fonts in Flash IDE. Now I'm making localization and my issue is that embedded Futura font doesn't have non-english symbols. I've added correct ttf font:

[Embed(source="../../../../../assets/fonts/FuturaBT-ExtraBlackCondensed.ttf", fontFamily="Futura Extra Black Condensed BT", mimeType="application/x-font", embedAsCFF="false")]
private const FONT_FUTURA_EXTRA_BLACK_CONDENSED:Class;

I've removed all places in main code with Font.registerFont() It works, but when I check Font.enumerateFonts(false) to show all embedded fonts it shows some mess:

[trace] Fonts : embedded 21 / all 192
[trace]     Arial / regular / embeddedCFF
[trace]     Arial / bold / embedded
[trace]     Arial / regular / embedded
[trace]     Arial / regular / embedded
[trace]     Arial Black / regular / embeddedCFF
[trace]     Arial Bold / regular / embeddedCFF
[trace]     Arial Bold / bold / embedded
[trace]     DS-Digital / bold / embedded
[trace]     Futura Extra Black Condensed BT / regular / embedded
[trace]     Futura Extra Black Condensed BT / regular / embedded
[trace]     ITCOfficinaSans LT Book / bold / embedded
[trace]     ITCOfficinaSerif LT Book / bold / embedded
[trace]     Myriad Pro / regular / embedded
[trace]     Myriad Pro Bold / bold / embedded
[trace]     Myriad Pro Bold Condensed / bold / embedded
[trace]     Myriad Pro Light / bold / embedded
[trace]     Myriad Pro Semibold / bold / embedded
[trace]     Rockwell Extra Bold / regular / embedded
[trace]     Times New Roman / regular / embeddedCFF
[trace]     VAG Rounded BT / regular / embedded
[trace]     VAG Rounded LT CYR Bold / bold / embedded

I'm worried that invalid Futura Extra Black Condensed BT is still there. So I have 2 questions:

1. How to find source of those embed fonts?

2. Is there way to remove or hide font after it was embedded somehow?
