C语言里的变异错误error:stray✀尀243✀in program是什么意思啊？

error:stray'\243' in program
错误：程序中的243
例句
1、the principle and method to deduce wavefront error due to stray light fringe pattern;
引起波面测量误差的干涉场杂纹消除的原理和方法；
2、In the tissue impedance spectroscopy measurements, four-electrode method are normally used. A measurement error caused by stray capacitance between lines of drive electrode and receive electrode is not a trivial problem.
在生物组织复阻抗谱测量中，通常采用四电极测量方法，相邻驱动电极和测量电极导联线间存在寄生杂散电容，本文研究了这一杂散电容对组织复阻抗实部和虚部测量精度的影响。
3、Pre-launch calibration of the FY-2B's visible channels has much error due to the influence of stray light.
FY2B由于杂散光的影响，其可见光通道的发射前定标存在较大误差。
4、The testing results show that the linearity is good, the uniformity error is within 7 ‰, the stray light is smaller than 1 μ W, the repeatability error is within 7 ‰, and the long stability error is within 8 ‰.
测试结果表明：线性比较好，均匀性误差在7‰以内，杂光小于1μW，重复性误差小于7‰，长期稳定性误差小于8‰。
5、The PST of stray light includes the influence of system assemble error, and reflects the real capacity of stray light suppression.
光学系统杂光指标PST的测量，包含了系统各种安装误差的影响，体现了系统杂光抑制的真实水平。

表述'\243'这个字符不能识别，应该是用的中文输入法输入标点符号，把问题指向的语句重新用英文输入法输一次就行了。
