Don't use clean(). It strips accented letters (à, é, ó) along with the invalid characters. The document only fails to save because of invalid XML control characters in the source text, so remove just those with regexreplaceall("[\x00-\x08\x0B\x0C\x0E-\x1F]", yourText, "") and keep the template UTF-8 encoded.

Few Samples

a!localVariables(
  local!samples: {
    "Gerente, Revisión de Crédito",
    "Café à la française",
    "Bad" & char(8) & "control" & char(11) & "chars",
    "Mix: José" & char(8) & " García ó"
  },
  a!forEach(
    items: local!samples,
    expression: {
      withClean: clean(fv!item),
      withRegex: regexreplaceall("[\x00-\x08\x0B\x0C\x0E-\x1F]", fv!item, "")
    }
  )
)

Glyphs are the visuals symbols for each character included in the font file. There is no way to add them. Try to use the default font for testing.

Hi Stefan Helzle I am using the Tahoma font in the template html expression. But I am not aware of the glyphs or how to include it to the template.

Could it be that you are using a custom font? If yes, does this font include the glyphs for these letters?
