Remove FontTranscoder
​https://bugs.webkit.org/show_bug.cgi?id=122088

Reviewed by Andreas Kling.

This overly generic class just implements mapping of backslash to yen symbol for some legacy Japanese fonts.

(WebCore::useBackslashAsYenSignForFamily):

Move the family set to Font.cpp.

(WebCore::Font::Font):
(WebCore::Font::operator=):
(WebCore::Font::update):

Keep the cached boolean up to date.

  • platform/graphics/Font.h:

(WebCore::Font::useBackslashAsYenSymbol):

Use descriptive name instead of talking about "transcoding".

  • platform/text/transcoder: Removed.
  • platform/text/transcoder/FontTranscoder.cpp: Removed.
  • platform/text/transcoder/FontTranscoder.h: Removed.
  • rendering/RenderText.cpp:

(WebCore::RenderText::RenderText):
(WebCore::RenderText::computeUseBackslashAsYenSymbol):

Rename for clarity.
Avoid unnecessary hash lookup, just check the cached bit in Font.

(WebCore::RenderText::styleDidChange):
(WebCore::RenderText::setTextInternal):

"Transcoding" here was just a simple character replacement.

(WebCore::RenderText::textWithoutConvertingBackslashToYenSymbol):

Renamed.
