As many/most of us know, there's an internationally standardized pictogram (symbol) for exit signs that's common in many countries worldwide. However, it's not yet common in the US, likely due to what appears to be a misconception that the IBC/IFC only allows "EXIT" lettering.
IBC/IFC Section 1013.5 requires internally illuminated exit signs to be listed to UL 924. (There's a different section on externally-illuminated exit signs, 1013.6.1, that specifies "EXIT" lettering, however, the vast majority of exit signs are internally-illuminated and therefore not subject to anything under 1013.6 due to that section's scope clause.) UL 924 was revised a while back to allow the internationally standardized pictogram, including in lieu of "EXIT" lettering. (see section 42 of UL 924) Therefore, my impression is that a UL-listed internally-illuminated exit sign that uses the internationally-standardized pictogram complies with the IBC/IFC. (There are such products currently on the market.) Are UL-listed internally-illuminated exit signs using the pictogram in compliance with IBC/IFC? Sent in anonymously for discussion.

I don't have an answer to this question, but this is an interesting question for me to see.

I think you made your own argument for, and rightly justified the answer as Yes.

That commentary language has an error, as it entirely ignores section 42 of UL 924.

Pictogram exit signs that are internally illuminated and meet UL 924 standards are compliant with IBC and IFC regulations.
