THotPDF.ResolveFontForCodePoint Method

Finds the first configured face that contains a requested Unicode scalar

Declaration

function ResolveFontForCodePoint(CodePoint: Cardinal;
  const PrimaryFontName: AnsiString;
  out ResolvedFontName: AnsiString): boolean; overload;
function ResolveFontForCodePoint(CodePoint: Cardinal;
  const PrimaryFontName: AnsiString; const FontStyle: TFontStyles;
  out ResolvedFontName: AnsiString): boolean; overload;

Parameters

• CodePoint is the Unicode scalar to resolve
• PrimaryFontName is checked before any fallback face
• FontStyle requests the same bold and italic face for primary and fallback coverage checks
• ResolvedFontName receives the selected installed face

Return value

Returns true when the primary face or a configured fallback contains the scalar

Usage notes

• The matching script chain is checked before hfsCommon
• Silent operating-system substitution does not count as coverage by the requested face
• False leaves callers able to record or replace the unresolved scalar explicitly
• The original overload checks regular faces; the explicit-style overload includes the requested face style in the bounded coverage cache
• Use an installed font family name such as Arial; PDF font names and resource keys are not system font family names
