Use "find ./linux/* | grep Kconfig | xargs file | grep UTF", can find
files with utf-8 encoded characters, these files will display garbled
characters in menuconfig, except for characters with special meanings
that cannot be modified, modify the characters with obvious errors to
eliminate the wrong display under meunconfig.

I did suggest fixing everything at once.  But I think there are
actually two problems here.  The first is that some are just wrong,
e.g., drivers/pci/Kconfig using CYRILLIC SMALL LETTER DZE instead of
"s", or net/netfilter/ipvs/Kconfig using NO-BREAK SPACE for no good
reason.

arch/Kconfig looks like it's using RIGHT SINGLE QUOTATION MARK instead
of the basic APOSTROPHE.  That one is debatable; I think it's fair to
argue that RIGHT SINGLE QUOTATION MARK would be preferred if rendered
correctly.

The second problem is that I think menuconfig doesn't handle UTF-8
correctly.  For example, in a gnome terminal with the default
LC_ALL=en_US.UTF-8, these look fine:

  $ grep -A10 MTD_SPI_NOR_USE_4K_SECTORS drivers/mtd/spi-nor/Kconfig
  ...
  64 KiB block instead of 16 × 4 KiB sectors.

  $ grep -A1 MTD_NAND_CAFE drivers/mtd/nand/raw/Kconfig
  config MTD_NAND_CAFE
	tristate "OLPC CAFÉ NAND controller"

But when menuconfig in the same terminal displays that same text, it
looks like "16  ~W 4 KiB sectors" and "OLPC CAF ~I NAND".

On the other hand, gconfig and xconfig do render these correctly.  So
I think there's something wrong with UTF-8 in menuconfig, and we
should fix that as well.

Anyway, I'm fine with this patch as far as it goes:

Menuconfig renders as "Clang ~@~Ys forward-edge", so this really
should be fixed.

I applied this one by itself to the PCI tree.

Menuconfig renders this one fine either way, as far as I can tell.
It contains several "c2a0" (UTF-8 non-breaking space) characters:

There are a few more ugly ones:

  $ find * -name Kconfig\* | xargs grep --color -rIP "[^[:ascii:]]"
  crypto/Kconfig: an ε-almost-∆-universal hash function, and an invocation of

CRYPTO_ADIANTUM
Renders as "an   -almost- ~H~F-universal hash function"

  drivers/mtd/nand/raw/Kconfig:	tristate "OLPC CAFÉ NAND controller"
  drivers/mtd/nand/raw/Kconfig:	Use NAND flash attached to the CAFÉ chip designed for the OLPC

MTD_NAND_CAFE
Renders as "OLPC CAF ~I NAND controller".

  drivers/mtd/spi-nor/Kconfig: 64 KiB block instead of 16 × 4 KiB sectors.

Renders as "64 KiB block instead of 16  ~W 4 KiB sectors."

  drivers/net/can/usb/Kconfig:from Theobroma Systems like the A31-µQ7 and the RK3399-Q7

CAN_UCAN
Renders as "from Theobroma Systems like the A31-  Q7 and the RK3399-Q7"

  drivers/net/can/peak_canfd/Kconfig: operated with ambient temperatures in a range of -40 to +85 °C.

CAN_PEAK_PCIEFD
Renders as "operated with ambient temperatures in a range of -40 to
+85   C."

  drivers/gpu/drm/panel/Kconfig: The panel has a 1200(RGB)×1920 (WUXGA) resolution and uses

DRM_PANEL_JDI_LT070ME05000
Renders as "The panel has a 1200(RGB) ~W1920 (WUXGA) resolution"

  drivers/gpu/drm/panel/Kconfig: panel module. The panel has a 1024×600 resolution and uses

DRM_PANEL_TDO_TL070WSH30
Renders as "panel module. The panel has a 1024 ~W600 resolution"

  drivers/platform/mellanox/Kconfig: The processor used on SN2201 is Intel Atom®Processor C Series,

CONFIG_NVSW_SN2201
Renders as "The processor used on SN2201 is Intel Atom  Processor C Series,"
(Not terrible, just an extra space, but lost the (R))

  drivers/platform/mellanox/Kconfig: System equipped with Nvidia®Spectrum-1 32x100GbE Ethernet switch.

Also CONFIG_NVSW_SN2201
Renders as "System equipped with Nvidia  Spectrum-1 32x100GbE Ethernet switch."
(Again, just an extra space but lost the (R))

  kernel/time/Kconfig:	int "Clocksource watchdog maximum allowable skew (in μs)"

CLOCKSOURCE_WATCHDOG_MAX_SKEW_US
Renders as "Clocksource watchdog maximum allowable skew (in   s)"
Clearly wrong.

Same problems exist in 'nconfig'.
