Using an arbitrary string for the replacement value in -replace can lead to unexpected results. The problem lies with unexpected replacement markers inside the replacement string, like $_, $1, etc. To avoid this, the $ character inside the replacement string must be escaped. Another solution is to simply use string's Replace(), which does literal replacement.
