However, *StringReplace[expr, "\\" -> "\\\\"]* works.
. Note, that expr needs some additional editing before being converted
because "\b" is an ASCII escape sequence for "Bell" and it is converted
-- more or less -- to its numeric value. Therefore "\beta" becomes
"\.08eta" :)
. Also, depending on your settings, Mathematica can automatically
convert the escape character "\" into "\\" when pasting a string.
In[2]:= expr = "\ln{H}^{*} &= {X}_{1} {\beta}_{1} + \
{\alpha}_{1}lnE+ {\varepsilon}_{1}"
Out[2]= "\\ln{H}^{*} &= {X}_{1} {\.08eta}_{1} + {\\alpha}_{1}lnE+ {\
\\varepsilon}_{1}"
. Finally, the string must start and end with a dollar sign "$" that
denotes math mode in LaTeX.
StringReplace[
"$" <> "ln{H}^{*} &= {X}_{1} {\\beta}_{1} + {\alpha}_{1}lnE+ \
{\varepsilon}_{1}\\" <> "$", "\\" -> "\\\\"]
ToExpression[%, TeXForm]
(Note that TeXForm is entered without double quotes.)
