Garbled characters in popup windows

[yamam]

When displaying a popup window with LspPeekDefinition, etc., garbled characters occur if the encoding of the file is different from the vim's internal encoding. I have confirmed that by converting the encoding after readfile in handle_location of vim.vim as follows, the characters are not garbled.

                call map(l:lines, 'iconv(v:val, &fileencoding, &encoding)')

There were other processes that used readfile, so similar measures may be necessary.
