Problem on remote jump to NamedDestination in unicode PDF

-

hello,

i'm writing application reads nameddest out of pdf file , gives opportunity view them opening document in acrobat reader , jumping named destination.
this works good, if named destination defined unicode string, there documents doesn't work.
first of all: tried use acrobat reader activex , possibility of running reader , remote control dde. works both same effect, not hope problem lies on communication.

to check why doesn't work, made test pdfs. if there few named destinations within pdf (but unicode strings) works. added 100 named destinations , didn't work.
i looked within text editor , there following change in '/dests' tag:

working:
...
<</dests 121 0 r>>
endobj
121 0 obj
<</names ...

not working (with many named dests):
<</dests 121 0 r>>
endobj
121 0 obj
<</kids[122 0 r 123 0 r]>>
endobj
122 0 obj
<</limits[...]/names ...

it seems '/limits' tag or '/kids' tag not work acrobat reader. did realize related problem or false direction?

it great if has hint me, how solve problem.

best regards,
volker

i'm struggling dht11 sensor work on arduino. code compiles without problems in serial monitor output keep on getting " read sensor: time out error" i've tried multiple libraries, adafruit etc still none of them worked. set serial monitor same speed (115200) didn't fix problem.  i'm using:  mega2560  dht11 temp+hum sensor windows10 x64 arduino 1.6.9 library dht11.h v0.4.1 source:  http://playground.arduino.cc/main/dht11lib wiring : blue = gnd yellow = 2 red = 5v (also see picture)  my code:    code: [select] #include <dht11.h> // //   file:  dht11_test1.pde // purpose: dht11 library test sketch arduino // //celsius fahrenheit conversion double fahrenheit(double celsius) {   return 1.8 * celsius + 32; } // fast integer version rounding //int celcius2fahrenheit(int celcius) //{ //  return (celsius * 18 + 5)/10 + 32; //} //celsius kelvin conversion double kelvin(double celsius) {   return ...

hi, sorry, new , unsure lot of things, need clarification. haven't found information explains how , why things work, "do this, that" i following guide ( arduino-thermistor-temperature-sensor-tutorial ) connect thermistor arduino uno. here temperature sensor information: temp. sensor 2000r +-1% to92 part.no.:   kty81-210 name:   temp. sensor 2000r +-1% to92 description:   2.5mm, 1980...2020ohm, -55...+150°c and here sensor's data-sheet: sensor data-sheet i have connected same way in guide. works , values being serial printed. what don't understand: 1. thermistor's , resistor's ohm value should equal, correct? in case 2000 ohm? 2. thermistor has ptc, i'm guessing have invert math or use ntc thermistor instead correct values? (currently resistance goes temperature goes down) 3. understand code uses steinhart-hart math logic convert resistor value temperature value, need a, b , c coefficients of thermis...
