Glulx text string dumps

I’ve been using “glulx-strings” (4.3.1) to get string dumps from ULX files, but it seems to omit a lot. I tried compiling a small program, and I couldn’t see any of my strings in the glulx-strings output. (Game title, author, the one room description, and a static string were not shown.)

Anyone know of a more robust string dumper?
