Error displayed while using 'qiime demux summarize' after importing the data

I have paired-end demultiplexed 16S rRNA data (fastq files). After importing the data on qiime2, I was running the command ‘qiime demux summarize’ and the following error shows up:

Plugin error from demux:

’utf-8’ codec can’t decode byte 0xb1 in position 4672: invalid start byte

Can anyone explain this error to me? How can I resolve this?
