What did you do?

Formatting a float for scientific results in extra spaces around the superscriptingExponent. ICU4C does not produce these same spaces when using unicode/scientificnumberformatter.h and CLDR does not suggest them either in current standards. See cel-go for the Go code.

What did you see happen?

1.052033 × 10⁰³

Note the extraneous NARROW NO-BREAK SPACE around the exponent separator.

What did you expect to see?

1.052033×10⁰³

Note the removal of the extraneous NARROW NO-BREAK SPACE around the exponent separator.

can you show a self contained reproducer in Go code without using cel.
