Magics does not plot all weekday names correctly for PNG/PDF output with LC_TIME=es_ES.UTF-8 #109
Description
What happened?
Magics does not plot all weekday names correctly for PNG/PDF output with LC_TIME=es_ES.UTF-8 (i.e., when CAIRO-PANGO is called).
What are the steps to reproduce the bug?
This is reproduced using the following Python script (based on Axis example 2):
#importing Magics module
from Magics.macro import *
ref = 'axis2'
#Setting of the output file name
output = output(
output_formats = ['png','ps','eps','pdf'],
output_name_first_page_number = "off",
output_name = ref
)
#Setting the cartesian view
projection = mmap(
subpage_y_position= 2.,
subpage_map_projection = 'cartesian',
subpage_x_axis_type = 'date',
subpage_y_axis_type = 'regular',
subpage_x_date_min = "2012-04-10",
subpage_x_date_max = "2012-04-28",
subpage_y_min = -20.,
subpage_y_max = 20.
)
#Vertical axis
vertical = maxis(
axis_orientation = "vertical",
axis_grid = "on",
axis_type = "regular",
axis_grid_colour = "grey",
axis_grid_thickness = 1,
axis_grid_reference_level = 0.,
axis_grid_reference_line_style='solid',
axis_grid_reference_thickness=2,
axis_grid_line_style = "dot"
)
#Horizontal axis
horizontal = maxis(
axis_orientation = "horizontal",
axis_type = "date",
axis_grid = "on",
axis_days_label_height = 0.4,
axis_months_label_height = 0.4,
axis_years_label_height = 0.4,
axis_grid_colour = "grey",
axis_grid_thickness = 1,
axis_grid_line_style = "dot"
)
lines =["Using time series...for units μm - should be micrometres with a Greek letter mu"]
title = mtext({
"text_lines" : lines,
"text_html" : "true",
"text_justification": "left",
"text_font_size": 0.75,
"text_colour" : "charcoal"
})
#To the plot
plot(output, projection, vertical, horizontal, title)
Run as:
$ env LC_TIME=es_ES.UTF-8 python3 axis2.py
Output shows error messages from CAIRO-PANGO:

Plot shows the day of the week for Wednesday - (mi)ércoles - isn't plotted:
Compare with eps output which correctly shows "mi":
This also happens with other locales (LC_TIME settings) - not just es_ES.UTF-8.
