Bar is not recognized as a unit

[anermina]

"unitsml(bar)" does not render as a unit but rather as a math symbol.

Example from OIML D 36:

of stem:[0.05 "unitsml(MPa)"]
(stem:[0.5 "unitsml(bar)"])

So the "bar" is recognised as the right unit. The problem is that it is being rendered as AsciiMath bar, instead of the string "bar". That can be fixed in the database.

... No it can't, it's a Plurimath issue, it is only happening on the .to_mathml, so the parsing of bar as a bar diacritic is happening there.

expr = '0.5 "unitsml(bar)"'

Plurimath::Math.parse(expr, "asciimath") == 
  <Plurimath::Math::Formula:0x0000000165c6e1a0
 @input_string="0.5 \"unitsml(bar)\"",
 @value=[#<Plurimath::Math::Number:0x00000001789374d8 @value="0.5">, #<Plurimath::Math::Function::Unitsml:0x0000000178936d58 @text="bar">]>

Plurimath::Math.parse(expr, "asciimath").to_mathml ==
  "<math xmlns=\"http://www.w3.org/1998/Math/MathML\" display=\"block\">\n  <mstyle displaystyle=\"true\">\n    <mn>0.5</mn>\n    <mo rspace=\"thickmathspace\">&#x2062;</mo>\n    <mrow>\n      <mstyle mathvariant=\"normal\">\n
