bug: Wrong hyperlink generated if filename contains both CJK characters and spaces

[wzxu]

Consider the following 4 filenames:

1. Test123.txt
2. Test 123.txt
3. 測試123.txt
4. 測試 123.txt

All first 3 work normally, but only the 4th one, containing both CJK characters and spaces, generates broken filename in the link, depending on the terminal used.

• Reference result by ls --hyperlink: %e6%b8%ac%e8%a9%a6%20123.txt
• Result in iTerm2: %25E6%25B8%25AC%25E8%25A9%25A6%20123.txt
  • (3rd one is %E6%B8%AC%E8%A9%A6123.txt so here we have many redundant 25 appearing in the link)
• Result in Ghostty/Alacritty/Zed: %E6%B8%AC%E8%A9%А6 123.txt
  • By the way the 2nd one is shown as just Test 123.txt rather than Test%20123.txt but it opens fine.

(Also won't work in WezTerm, or kitty, but they don't show the link content so I don't know what it looks like for them.)

• The version of eza being used (eza --version)
  • v0.20.7 [+git]
• The command-line arguments you are using
  • eza --hyperlink
• Your shell and terminal
  • iTerm2, Ghostty ($TERM = xterm-256color for both)
• Your operating system and hardware platform
  • macOS 14.6.1
