Delphi:从Windows-1251转换为Shift-JIS [英] Delphi: Convert from windows-1251 to Shift-JIS
问题描述
我有一个字符串’MIROKU’
。我想将此字符串转换为’%82l%82h%82q%82n%82j%82t’
。以下是我当前用于转换的函数:
I have a string 'MIROKU'
. I want to convert this string to '%82l%82h%82q%82n%82j%82t'
. Below is my current function which I have used for converting:
function MyEncode(const S: string; const CodePage: Integer): string;
var
Encoding: TEncoding;
Bytes: TBytes;
b: Byte;
sb: TStringBuilder;
begin
Encoding := TEncoding.GetEncoding(CodePage);
try
Bytes := Encoding.GetBytes(S);
finally
Encoding.Free;
end;
sb := TStringBuilder.Create;
try
for b in Bytes do begin
sb.Append('%');
sb.Append(IntToHex(b, 2));
end;
Result := sb.ToString;
finally
sb.Free;
end;
end;
MyEncode('MIROKU',932)
返回'%82%6C%82%68%82%71%82%6E%82%6A%82%74'
。我没想到会有这个结果。我期望’%82l%82h%82q%82n%82j%82t’
。有任何函数可以正确转换它?
MyEncode('MIROKU', 932)
returns '%82%6C%82%68%82%71%82%6E%82%6A%82%74'
. I don't expect this result. I expect '%82l%82h%82q%82n%82j%82t'
. Are there any functions to convert it correctly?
推荐答案
您所看到的是正确的,而不是您所期望的。例如,%6C
是 l
的ascii表示。因此,您可以尝试这样的事情:
What you are seeing is correct, just not what you are expecting. %6C
, for example, is the ascii representation for l
. So you could try something like this instead:
function MyEncode(const S: string; const CodePage: Integer): string;
var
Encoding: TEncoding;
Bytes: TBytes;
b: Byte;
sb: TStringBuilder;
begin
Encoding := TEncoding.GetEncoding(CodePage);
try
Bytes := Encoding.GetBytes(S);
finally
Encoding.Free;
end;
sb := TStringBuilder.Create;
try
for b in Bytes do begin
if (b in [65..90]) or (b in [97..122]) then
begin
sb.Append( char(b)); // normal ascii
end
else
begin
sb.Append('%');
sb.Append(IntToHex(b, 2));
end;
end;
Result := sb.ToString;
finally
sb.Free;
end;
end;
或者您可以保留它!
