Backport #22814. The use of `sort.Search` is wrong: The slice should be sorted, and `return >= 0` doen't mean it exists, see the [manual](https://pkg.go.dev/sort#Search). Could be fixed like this if we really need it: ```diff diff --git a/modules/charset/escape_stream.go b/modules/charset/escape_stream.go index 823b63513..fcf1ffbc1 100644 --- a/modules/charset/escape_stream.go +++ b/modules/charset/escape_stream.go @@ -20,6 +20,9 @@ import ( var defaultWordRegexp = regexp.MustCompile(`(-?\d*\.\d\w*)|([^\` + "`" + `\~\!\@\#\$\%\^\&\*\(\)\-\=\+\[\{\]\}\\\|\;\:\'\"\,\.\<\>\/\?\s\x00-\x1f]+)`) func NewEscapeStreamer(locale translation.Locale, next HTMLStreamer, allowed ...rune) HTMLStreamer { + sort.Slice(allowed, func(i, j int) bool { + return allowed[i] < allowed[j] + }) return &escapeStreamer{ escaped: &EscapeStatus{}, PassthroughHTMLStreamer: *NewPassthroughStreamer(next), @@ -284,14 +287,8 @@ func (e *escapeStreamer) runeTypes(runes ...rune) (types []runeType, confusables } func (e *escapeStreamer) isAllowed(r rune) bool { - if len(e.allowed) == 0 { - return false - } - if len(e.allowed) == 1 { - return e.allowed[0] == r - } - - return sort.Search(len(e.allowed), func(i int) bool { + i := sort.Search(len(e.allowed), func(i int) bool { return e.allowed[i] >= r - }) >= 0 + }) + return i < len(e.allowed) && e.allowed[i] == r } ``` But I don't think so, a map is better to do it. |
