Oh boy, neither GCC nor Clang liked the Unicode one bit:

Thank you. This issue is discussed here https://github.com/akinomyoga/cxxmatrix/issues/3

It is caused by the UTF-8 unaware awk. I haven't yet figured out why it happens, but at least you need to set your locale to one of UTF-8 locales.

You made it further than I did. The majority of machines out there today probably do not support the required -std=c++17. I know none of my OS installs (and their compilers) do.

[saagarjha]

I think Xcode has shipped with a compliant C++17 compiler for over a year, but I used GCC to compile this one :)

[fhars]

GCC has supported this for more than a year, too (at least since 7.4.0).

[saagarjha]

GCC 7.4.0 sadly misses certain C++ features (filesystems) and does not correctly support others (template argument deduction). I'm waiting for 20.04 to hopefully bump GCC to something newer…

I was able to fix it by find all 'ï' and replace with '\U000000EF' in glyph.inl

I fixed this on my mac (High Sierra) with:

brew install gawk

make clean

make

And shortly after, I did this:

brew cask install iterm2
