Bug: Word output error with < symbol from formatting function

[ddsjoberg]

Description

Hello! 🍁

There seems to be an escaping issue in Word output when a formatting function applied via fmt() uses a less than symbol.

In the example below, I am formatting all number less than one to be displayed as <1 instead of their true value. The result should be the Word version of this table.

Thank you!

Reproducible example

packageVersion("gt")
#> [1] '0.9.0.9000'

tibble::tibble(x = c(0.5, 1, 2)) |> 
  gt::gt() |> 
  gt::fmt(fns = \(x) ifelse(x < 1, "<1", as.character(x))) |>
  gt::gtsave("test.docx")
#> Error in read_xml.raw(charToRaw(enc2utf8(x)), "UTF-8", ..., as_html = as_html, : StartTag: invalid element name [68]

Dan, I just tried out that example in my build of gt (which is at the most recent GH commit) and it works fine! I think that @thebioengineer fixed this as part of #1401. Could you update to the very latest and verify on your end?

Oh goodness, my dev version was a couple of weeks out of date and didn't update. Thank you and apologies! Looks great!!
