错误 X3000：着色器文件中存在非法字符

我粘贴了一行着色器代码，现在我的项目无法工作。

• 我删除了受污染的代码行。

• 我已经按照 VS、Notepad 和 Notepad++ 的建议从头开始多次重写着色器Unity 论坛.

• 我在 Notepad++ 中使用了十六进制编辑器视图来排除前两个字节不是0xFE 0xFF正如建议的那样游戏开发问题.

这个我实在想不通。我很感激您提出的任何建议。

cbuffer CB_PER_FRAME : register(b0)
{
    column_major float4x4 view;
    column_major float4x4 proj;
    float4 eyePosition;
};

struct VertexInput
{
    float3 position : POSITION;
    float3 normal   : NORMAL;
    float2 texCoord : TEXCOORD;

    row_major float4x4 world : WORLD;
    float4 color : COLOR;
    uint instanceID : SV_InstanceID;
};

struct PixelInput
{
    float4 position : SV_POSITION;
    float3 normal   : NORMAL;
    float2 texCoord : TEXCOORD;
    float4 color    : COLOR;
};

PixelInput VertexShaderMain( VertexInput vertexInput )
{
    PixelInput pixelInput (PixelInput)0;

    pixelInput.position = mul( float4( pixelInput.position, 1.0f ), vertexInput.world );
    pixelInput.position = mul( pixelInput.position, view );
    pixelInput.position = mul( pixelInput.position, proj );

    pixelInput.normal = normalize( mul( pixelInput.normal, (float3x3)vertexInput.world ) );
    pixelInput.texCoord = vertexInput.color;
    pixelInput.color = vertexInput.color;

    return pixelInput;
}

float4 PixelShaderMain( PixelInput pixelInput ) : SV_Target
{
    return pixelInput.color;
}

It was an encoding problem. When I pasted the line of code it somehow made my compiler treat every text file as UNICODE instead of ASCII. This caused the problem.
The solution was opening the shader file in Visual Studio and go to
File->Save as->Save with Encoding and then choose the correct format and rebuild the solution.
