The diacritical symbols are clipped

[janco]

Hello. I tried to edit some TTF-font to add the deficient symbols with diacritic such as àâ to it.

First I increased Winascent value for enough space to put over these diacritic. Then created new glyphs ÀÁÃ and mapped to latin 1252 (active checkbox is set). In fact I can preview all them well in Type 3.2, but when I save the font with added new glyphs, I can't use it, because all the diacritical signs are clipped and characters ÀÁÃ are displayed AAA with nothing, although the added diacritics are under Winascent. All drawed below 0-windescent is displayed, and all between 0-capsheight, but all between capsheight-winascent is clipped. Why? How can I fix it?

Can you help me?

I attached 2 files:

ASIA_AS2.ttf - it is the original

ASIA_AS3.ttf - that one, which I modified and with clipped diacritics.

You are correct in adjusting the Winascent value, but the original font also contains a VDMX (vertical metrics table), which contains metrics from the original font. You just need to save your font without the VDMX table.

Go to font options on the font menu and uncheck the box next to VDMX before saving your font.

Modified version attached.

Thank you, Allan so much. I didn't know about VDMX, and thought that increasing winascent would enough. Now it looks fine =)
P.S. You may close the topic [solved].
