Find solution for the “Geminated El”

This could be solved via language-aware contextual GSUB, or contextual GPOS.

[miguelsousa]

I think you don't even need to make the contextual GSUB language-aware, if you include the second L in the context.

[frankrolf]

@miguelsousa I have been thinking about that, I wonder how many people would “decorate” type like this: ·h·e·l·l·o·.
Edge case or eBay feedback?

[miguelsousa]

Those people MUST get the geminated L.

Don’t they use middle dot in dictionaries to indicate hyphenation?

[frankrolf]

No, the middle dot is used to indicate a two-syllable word, such as instal·lacion. Without the dot, the ll would be pronounced similar to j, as in relleno. Since the middle dot is easy to access on the keyboard, it has become the standard approach (sometimes, you’ll also see the period being used).

[frankrolf]

I may have misread the “they”:
In dictionaries, I feel like the bullet character is more commonly used between syllables.

The interpunct we use for l·l is U+00B7. For dictionary usage, U+2027 should be used.

[frankrolf]

I decided to address this through contextual kerning.
I also decided to not hide that kerning behind a language tag – the combination is fairly unique. This makes bugs like adobe-fonts/source-code-pro#192 possible, but I believe this edge case is outweighed by the usefulness of this solution for Catalan text.

I wrote a script which basically mimics the composition & advance width of the (obsolete, but nevertheless present in the UFOs) ldot glyph, when l · l are typed.

The script is here:

In the latest release of Source Serif, the combination l · l will now automatically reposition the centered period for a more even word image.
Please report back in case of unexpected/suboptimal behavior!
