本文介绍了一个用于从中文字符串中提取每个汉字对应的拼音首字母的Delphi/Pascal函数实现。该函数通过判断汉字的Unicode编码范围来确定其对应的拼音首字母，并能够处理多种中文字符。

unction CnPYIndex(const CnString: string): string;
{
返回中文的拼音首字母
}
const
ChinaCode: array[0..25, 0..1] of Integer = ((1601, 1636), (1637, 1832), (1833, 2077),
    (2078, 2273), (2274, 2301), (2302, 2432), (2433, 2593), (2594, 2786), (9999, 0000),
    (2787, 3105), (3106, 3211), (3212, 3471), (3472, 3634), (3635, 3722), (3723, 3729),
    (3730, 3857), (3858, 4026), (4027, 4085), (4086, 4389), (4390, 4557), (9999, 0000),
    (9999, 0000), (4558, 4683), (4684, 4924), (4925, 5248), (5249, 5589));
var
i, j, HzOrd, l_iHz: Integer;
Hz: AnsiString;
begin
i :=  1;
l_iHz :=1;
  while i <= Length(CnString) do
  begin
    Hz := CnString[i];
    if (Hz[l_iHz] >= #160) and (Hz[l_iHz +1] >= #160) then
    begin
      HzOrd := (Ord(Hz[l_iHz]) -160) *100+ Ord(Hz[l_iHz +1]) -160;
      for j :=0to25do
      begin
        if (HzOrd >= ChinaCode[j][0]) and (HzOrd <= ChinaCode[j][1]) then
        begin
          Result := Result + Char(Byte('A') + j);//改A为a就全部是小写
          Break;
        end;
      end;
    end
    else
      Result := Result + CnString[i];
    Inc(i);
  end;

end;
