gt.save() not rendering dash character correctly ("-")

[nedransfield]

I am trying to render a table as a png, but it seems to be having issues with some negative numbers in the table. When I render the table in a browser with gt.show(), it looks how I expect it to. However, when I use gt.save(), it seems the negative sign gets encoded as something else.

Here is gt.show()

And here is gt.save()

I am creating the table from a pandas data frame

table = (
        GT(pitcher_report)
        .tab_header(title='Pitch Stats') # Table title
        .tab_spanner(label='Usage', columns=['Frequency', 'Uses']) # Column group for 'Frequency' and '# uses'
        .tab_spanner(label='Velocity (MPH)', columns=['RelSpeed', 'Max']) # Column group for 'Avg velo' and 'Max velo'
        .tab_spanner(label='Movement (Inches)', columns=['InducedVertBreak', 'HorzBreak']) # Column group for 'IVB' and 'HB'
        .tab_spanner(label='Release (Feet)', columns=['RelHeight', 'RelSide', 'Extension']) # Column group for 'Height', 'Side', and 'Extension' 
        .cols_label(RelSpeed='Avg', InducedVertBreak='IVB', HorzBreak='HB', RelHeight='Height', RelSide='Side', Extension='Ext', SpinRate='Spin Rate') # Relabeling columns for readability
        .tab_stub(rowname_col='TaggedPitchType') # Row labels
        .fmt_percent(columns='Frequency') # formatting Frequency as %
        .fmt_number(columns=['RelSpeed', 'Max', 'SpinRate'], decimals=1) # formatting columns to 1 decimal place
        .fmt_number(columns=['InducedVertBreak', 'HorzBreak'], pattern='{x}"', decimals=1) # formatting inches columns
        .fmt_number(columns=['RelHeight', 'RelSide', 'Extension'], pattern="{x}'", decimals=1) # formatting feet columns
        .opt_stylize(style=1, color='blue')
    )

table.show()
table.save('table.png')

Any ideas on why this is happening?

Also occasionally, gt.save() Has left out a row from my table but that has been inconsistent...

As I have continued to play around with it, it seems to be caused by the formatting methods. When I comment out the fmt_number line that pertains to the negative values, the encoding issue goes away. I also tried a negative value in the fmt_percent column and experienced the same encoding issue that the other column has.

Again, the issue only appears in the png that gets saved by table.save

@nedransfield, could you please try using the latest version, "v0.17.0," to see if the issue is resolved?

@jrycw, seems to be working now. Thank you!
