Hi,
During my work I have find some issue, i request to enhancement please… thank you:
1- about adding set left side … x=0 left side bearing to transformer wizard because some glyphs missed out x=0 when using this wizard, i don’t know why?.
2- about adding win Descent and win Ascent to open type designer window, so the users will ensure that mark positions not to be outside.
3- about make user able to multi select glyphs in new substitution window.
- Is already available.
- Using glyph classes would save time in the long run. jeem-arab, hah-arab, khah-arab could be in one class, reh-arab, zain-arab in another, and seen-arab, sheen-arab in another.
Thanks Bhikkhu, that is a good lesson… your student 
I see your Transform Wizard window, there is a script: “left side bearing point at x=0”. I use version 14.0.0.2814 and the script doesn’t exist. Do you know where did they move the script?
With version 14 the left side bearing point is always set at x=0, so the option is no longer available.
Erwin, thanks for the reply.
But if the left side bearing point is always set at x=0, why the generated font have this problem?
Even though I have set the metrics and kerning carefully.
Do send the font project file to us and we will look into it.
This is the fcp file, thanks.

In your export settings you have set OpenType Layout Features to No, so the kerning is not part of your exported font.
I have followed your instructions, but there is no change. (already uninstall the last font, and install the new one to windows).
Oh sorry, you mean that I have to change the open type layout feature to yes?
Yes, the kerning is part of the OpenType layout features.
Also be aware you need to manually enable kerning in Word.
Erwin, when I change the opentype layout feature to yes, the result is the same, no change 
It works just fine here, so you must be doing something wrong.
Where do you test, and did you make sure kerning is enabled?
Does Notepad support kerning?
Fix side-bearing first, then apply kerning for those pairs like AW, or vy where kerning is needed.
Erwin, I tested it on Notepad & Word.
Hmm.. maybe I have to review it all again.
Btw, thank you for all the input
Test your font in Word, or another application (LibreOffice) that supports OpenType features.
