First of all, your pattern for Th is incorrect: fio  = "T|h", doesn't make much sense.

Anyway, even with this corrected I can confirm the behaviour.

Betreff: Re: [NTG-context] blockligatures removing characters

Thanks Hans,

I tried to modify your example for preventing the capital-Th ligature but this doesn't seem to work. The 'fi' ligature is prevented, but 'Th' still appears as a ligature. This occurs with the original lowercase version too. Have I missed something?

```
\startluacode
     local demo = {
         name    = "demo",
         options = {
             {
                 patterns = {
                     fio  = "f|io",
                 },
                 words = [[ fioot fiots ]],
             },
             {
                 patterns = {
                     fio  = "T|h",

I'll fix it but it's not the way to do it in lmtx where we have

\startluacode
     local demo = {
         name    = "demo",
         options = {
             {
                 patterns = {
                     fio  = "f|io",
                 },
                 words = [[ fioot fiots ]],
             },
             {
                 patterns = {
                     fio  = "t|h",
                 },
                 words = [[ this that ]],
             },
         },
     }
     table.save("oeps-fixes.llg",demo)

I just added (no upload) this

\startluacode
     local demo = {
         name    = "demo",
         options = {
             {
                 substitutions = {
                     th = "t|h",
                     Th = "T|h",
                     st = "s|t",
                     St = "S|t",
                     fi = "f|i",
                 },
             },
         },
     }
     table.save("oeps-fixes.llg",demo)
