Function: isolate()

isolate(value): string

Alpha

Wrap value in Unicode bidi isolates (FSI/PDI) so it doesn't scramble the surrounding text's direction — e.g. a Latin filename embedded in an Arabic sentence built with plain string concatenation. formatMessage already does this for MF2 placeholders; use isolate only when interpolating outside MF2.

Parameters

value

string

Returns

string
