Thanks Ben,
Changing './' and '.' and shQuote() didn't work. I'm trying dQuote().
For your information the 'name' value retrieved is --> Hội những người
đồng hành cùng
I guess the string is in Vietnamese language. As you would have
observed in error message it wasn't interpreted as above but some
other nonsensical characters (posts_H<U+1ED9>i nh<U+1EEF>ng
ngu<U+1EDD>i d<U+1ED3>ng
> hành cùng line).
Is there a workaround to handle such strings ?
Regards,
Sunny
