Dear Obspy Users

First of all thanks for your useful package. I’m using obspy for my doctoral program but I have problem with reading nano metrics Y-file which I have. As the attachment I sent you an example file I have.  
I would appreciate if you help me to solve this problem.  
I’ve tried to read it as “read” and “readY” but non of them work, and I got following error

Dear Meysam Rezaeifar,

there are some invalid non ASCII characters within the STATION\_INFO tag of your Y files. Ignoring them while reading the faulty file is probably the best approach - see [y: Ignore non ASCII characters in TAG\_STATION\_INFO · obspy/obspy@b1300e2 · GitHub](https://github.com/obspy/obspy/commit/b1300e25de0678f362738c6863c285b8a4926e7d) in order to fix your local version of ObsPy - future versions of ObsPy will have this fix included.

Cheers,  
Robert
