string containing ampersand generates ParaFrag in Paragraph.breakLines().lines

[Elena Williams]

from reportlab.platypus import Paragraph
from reportlab.lib.styles import ParagraphStyle

## Expected behaviour:

STRING_GOOD = 'x x'
para = Paragraph(STRING_GOOD, ParagraphStyle('default'))
para.width = 500

plines = para.breakLines(500)
plines.lines
# Out: [(487.22, ['x', 'x'])]

## Unexpected behaviour:

STRING_ODD = 'x & x'
para2 = Paragraph(STRING_ODD, ParagraphStyle('default'))
para2.width = 500

plines2 = para2.breakLines(500)
plines2.lines
# Out: [ParaLines(ascent=7.18, descent=-2.07, extraSpace=487.22, fontSize=10, wordCount=2, words=[ParaFrag(bold=0, bulletText=None, fontName='Helvetica', fontSize=10, greek=0, italic=0, link=None, rise=0, strike=0, sub=0, super=0, text='x x', textColor=Color(0,0,0,1), underline=0)])]
