Fontlab is doing odd things when I compile my open type feature ( calt ).
1. While in unicode mode ( Unicode on the left & Latin A on the right, I was adding Latin A characters ) it removed the outlines form hbar glyph when I re-compiled my now altered calt feature. The odd thing was that I had no reference to 'hbar' in the code!
Should I start a new font & paste my content into it? I have heard some folks on Typophile talk about a source file going bad & needing to do this.
Now that I am in Names & Mac Roman mode again compiling my calt feature didn't wipe out the hbar outlines. It did find a missing Quotesingle glyph. Could that have been wiped out when I went into Unicode mode to add the latin A?
Are there safer & less safe modes to compile features in Fontlab?
And actually, what is the recommended roundtrip process ( with emphasis on mode changes ) for adding unicode glyphs & then testing them?
