normalization during transcoding

The text on the green background indicates the result.

The stylesheet was normalized to NFC.

The stylesheet was normalized to NFD.

No normalization took place.

Assertion: [Exploratory test] Text is not normalized during transcoding when the style sheet is in another encoding.

Notes:The imported style sheet is saved as Windows 1258 (Vietnamese code page). The selector contains the equivalent in that code page of U+00EA LATIN SMALL LETTER E WITH CIRCUMFLEX followed by U+0300 COMBINING GRAVE ACCENT. Under NFC, these merge. Under NFD, the first decomposes. If there is no green background, something has gone wrong.
