Hi Esra,

You are *still* incorrectly referring to the glyph with three dots over it:

"ژ" is *not* "ze"/U+632 - it is "zhe"/U+698.

Have you increased the font size?  Can you see the difference between these two?:

"ژ"/"zhe"/U+698
"ز"/"ze"/U+632

Like I keep saying, in the above description, you're using the glyph "ژ"/"zhe"/U+698, while
calling at the same time incorrectly referring to it as "ze"/U+632.

I don't mean to continually bang on about this - if you're *sure* that when you search, you're
using the character represented by the glyph with one dot (and not three), i.e. "ز"/"ze"/U+632,
then the problem lies elsewhere.
