Hello. I've tried to package PT Astra font

http://astralinux.com/fonts.html

But it's download URL contains ampersand sign (&).

http://astralinux.com/images/fonts/PTAstraSans&Serif_TTF_ver1001.zip

Guix returns

build failed: invalid character `&' in name
`PTAstraSans&Seif_TTF_ver1001.zip.drv'

How do I escape & in URL so guix accept it?

Try "%26", which is the hex-representation of the ascii-code of "&".

Instead of escaping it, add a ‘file-name’ field in the ‘origin’ form
that does not contain the offending character:

  (origin
    (method url-fetch)
    (uri …)
    (sha256 …)
    (file-name "the-font.zip"))

HTH!

Hello,

Where is this restriction coming from ?
Could the error message add some help/hint about "adding (file-name ...)" ?
