Package: mupdf
Version: 1.21.1+ds1-1
Recent versions of mupdf have a bug in the handling of '<' and '>'
characters in SVG output. For example, with the following file:
https://gnu.support/files/tmp/2023-01-05/FR%20205.pdf
mutool draw -o foo.svg 1
produces an invalid SVG file, with several occurrences of 'data-text="<" ... />'.
The function svg_dev_data_text should use the same logic as
svg_dev_text_span for these characters. Patch attached.
