48GX: Singapore vs Indonesia

[Benjer]

I wonder if it doesn't have something to do with the switch from dual-injected keys to printed keys. I believe I read somewhere that this transition took place while the 48G series was in production. I have to imagine there were at least some limitations to the characters or designs which could be injected into a key, as opposed to printed.

Perhaps at the time the powers that be felt they were making a desirable change to the character design on the keys.

This of course offers no explanation as to why the x on the sqrt key was more or less unchanged.
