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.
