if ch is that char,you can do this

if((ch.charCodeAt(0)>=a.charCodeAt(0) && ch.charCodeAt(0)<=z.charCodeAt(0))||(ch.charCodeAt(0)>=A.charCodeAt(0) && ch.charCodeAt(0)<=Z.charCodeAt(0)))

You can do the same comparison with arabic character

which is represented in unicode

[u0600-u06ff]|[u0750-u077f]|[ufb50-ufc3f]|[ufe70-ufefc]
