    svl: HTMLParser: stop inserting control character garbage into Writer
    
    E.g. rhbz433940-1.html contains literal ^G characters that are inserted
    as-is into SwTextNodes.
    
    This now triggers assert about CH_TXT_ATR_FIELDSTART in
    SwSubFont::GetTextSize_() that was added in
    19a559b0ec9b806519c405651d6d2b2e14712b4a.
