Ktfmt should ignore the UTF-8 BOM. #565
Description
In our codebase we had one Kotlin file, which first three bytes were the UTF-8 BOM 0xEF 0xBB 0xBF. Most tools ignore these three bytes, but ktfmt didn't and reported an error:
TestWithBom.kt:1:1: error: Expecting an element
It took a while to figure out what's wrong with the file, because the syntax is correct and most editors don't highlight these bytes. It's clear to me, that the UTF-8 BOM is redundant and we removed it, but it would be better, if ktfmt would ignore the BOM by default.
I attached a .zip file that contains two .kt files to reproduce the issue.
