if (!charCodes) {
          
          
          continue;
        }
        for (let i = 0, ii = charCodes.length; i < ii; i++) {
          const charCode = charCodes[i];
          
          
          const charCodeToGlyphId = newMapping.charCodeToGlyphId;
          const baseFontCharCode = createCharCode(
            charCodeToGlyphId,
            baseGlyphId
          );
          const accentFontCharCode = createCharCode(
            charCodeToGlyphId,
            accentGlyphId
          );
          seacMap[charCode] = {
            baseFontCharCode,
            accentFontCharCode,
            accentOffset,
          };
        }
      }
      properties.seacMap = seacMap;
    }
    const unitsPerEm = 1 / (properties.fontMatrix || FONT_IDENTITY_MATRIX)[0];
